Key test for 'pink wave' power in Tuesday's primaries The stakes for Democrats are high in Pennsylvania's primaries

Tuesday night's primaries featured redrawn district maps, a spate of retirements, a surging "pink wave" of candidates seeking to make history, and colorful political storylines aplenty.

All of these narratives converged in Pennsylvania — a state currently dominated by an all-male, largely Republican congressional delegation. The Keystone State is critical to Democratic hopes of retaking the House and that party hopes their female candidates will play a big role in that effort.

Primary voters also headed to the polls in Idaho, Nebraska, and Oregon.

Here's what you need to know about Tuesday's primaries.

1:00 a.m. - AP calls Idaho Democratic gubernatorial primary for Paulette Jordan

The Associated Press has called the Idaho Democratic gubernatorial primary for Paulette Jordan, a former state representative who, were she to win the general election, could be both the first woman and the first Native American woman to serve as the state's governor. Jordan is a member of the Coeur d'Alene Tribe.

12:43 a.m. - Here's how female candidates in the Keystone State fared

So far eight candidates have advanced in seven different congressional districts to the November general election in Pennsylvania:

PA-04: Madeleine Dean (D) PA-05: Mary Gay Scanlon (D), Pearl Kim (R) PA-06: Chrissy Houlahan (D) PA-07: Susan Ellis Wild (D) PA-11: Jessica King (D) PA-14: Bibiana Boerio (D) PA-15: Susan Boser (D)

Democratic candidate Judy Herschel narrowly trails her opponent Marc Friedenberg in the 12th Congressional District Democratic primary, but the AP has not yet projected that race. Democratic candidate Shavonnia Corbin-Johnson is also narrowly trailing her opponent George Scott in the primary for the state's 10th Congressional District, but 100% of precincts are reporting in that race, the AP has not projected that race either.

20 female candidates ran this year for the U.S. House this cycle (19 Democrats, 1 Republican) in 13 of Pennsylvania's 18 congressional districts.

12:41 a.m. -The latest roundup of primary wins

Pennysylvania:

1st Congressional District (Democratic primary): Wealthy entrepreneur Scott Wallace, whose grandfather is former Vice President Henry Wallace, defeated Navy veteran Rachel Reddick. Wallace, who lent his campaign $2.5 million, will now face GOP Rep. Brian Fitzpatrick in this Bucks County congressional district. Fitzpatrick is the only Philadelphia-area GOP congressman to neither retire nor resign.

5th Congressional District (Democratic primary): Attorney Mary Gay Scanlon defeated a crowded field of over 10 Democrats (including five other women) to win the Democratic nomination in this blue-leaning district. Scanlon will take on Republican Pearl Kim in November. Kim is the only Republican woman running for a U.S. House seat this cycle. The result ensures that Pennsylvania’s all-male congressional delegation will end next year when either Scanlon or Kim is elected and sworn-in.

7th Congressional District (Democratic primary): Allentown City Solicitor Susan Ellis Wild defeated two other primary challengers – Pastor Greg Edwards and Northhampton County DA John Morganelli – in this Lehigh Valley swing district. Wild will face either Lehigh County Commission Chair or Olympic gold medalist Marty Northstein or former Lehigh County Commissioner Dean Browning in the November general election (the GOP race has not yet been projected).

14th Congressional District (Republican primary): Exactly two months after he lost a special election in Pennsylvania's 18th Congressional District to Democrat Conor Lamb, GOP State Rep. Rick Saccone lost again tonight. Saccone lost the GOP primary in the state's 14th Congressional District (southwest of Pittsburgh) to GOP State Rep. Guy Reschenthaler. The seat is a deep red district that Reschenthaler will likely hold in November.

Oregon:

Governor (GOP primary): State Rep. Knute Buehler won the Republican primary for Oregon governor, fending off primary challenges from businessman Sam Carpenter and retired Navy Pilot Greg Woolridge. Buehler will take on incumbent Democratic Governor Kate Brown in November in a state that has not elected a Republican to the office since the 1980's.

Idaho:

Governor: Neither race has been projected by the AP, but right now State Rep. Paulette Jordan, who would be the first Native American governor in the country and first female governor of Idaho, is leading the Democratic primary over businessman A.J. Balukoff. On the GOP side, Lt. Gov Brad Little is leading the pack over GOP Rep. and House Freedom Caucus founder Raul Labrador. The state is staunchly Republican, but Democrats are hoping Jordan's unique background and populist appeal can make the race competitive in November.

Nebraska:

2nd Congressional District (Democratic primary): No winner has been projected between former U.S. Rep. Brad Ashford and first-time candidate/non-profit executive Kara Eastman, but current results have the two separated by less than 200 votes. Democrats have been worried that Eastman's more progressive policy positions may put her at a disadvantage to defeat GOP Rep. Don Bacon in November in a seat Hillary Clinton narrowly lost in 2016, and is a target this cycle in the Democrats attempt to retake the U.S. House.

11:26 p.m. - PA-14 GOP Primary: Rick Saccone loses (again)

Exactly two months after he lost a special election in Pennsylvania's 18th Congressional District to Democrat Conor Lamb, GOP State Rep. Rick Saccone lost again tonight.

Saccone lost the GOP primary in the state's 14th Congressional District (southwest of Pittsburgh) to GOP State Rep. Guy Reschenthaler. The seat is a deep red district that Reschenthaler will likely hold in November.

10:49 p.m. - AP calls in Pennsylvania and Nebraska primaries

Pennsylvania:

Governor (GOP primary): Pennsylvania senator and waste-hauling millionaire Scott Wagner won the GOP primary to challenge Democratic Gov. Tom Wolf. Wagner was facing a strong challenger from consultant Paul Mango, but held on for what looks to be a narrow victory. Wolf is a well-funded incumbent that most observers believe will win re-election to a second term in November.

U.S. Senate (GOP primary): Four-term US Rep. Lou Barletta, staunch Trump supporter, won the GOP nomination for US Senate in Pennsylvania. Barletta defeated State Rep. Jim Christiana for the nomination to take on Casey, one of 10 incumbent Democratic senators up for re-election this year in state's that Donald Trump won in 2016. The former Mayor of Hazelton also has the endorsement of President Trump, and could be someone we see POTUS hit the campaign trail for at some point during this cycle.

4th Congressional District (Democratic primary): State Representative Madeleine Dean defeated former U.S. Rep. Joseph Hoeffel and gun control advocate Shira Goodman. Dean will take on Republican Dan David in November in a solidly blue district.

6th Congressional District: Democrat Chrissy Houlahan, a U.S. Air Force Veteran and first-time candidate, will take on Republican Greg McCauley in November in this suburban Philadelphia district that is an open seat race due to GOP Rep. Ryan Costello's retirement.

17th Congressional District: The battle between two incumbents (who ran unopposed in the primary) is set -- Democratic Rep. Conor Lamb will take on Republican Rep. Keith Rothfus in this suburban Pittsburgh district that will be a key race in November to Democratic hopes of taking back the U.S. House.

The Democratic primaries in districts 1, 5, 7 and 10 have all not yet been projected.

Nebraska:

Governor (Democratic primary): State Sen. Bob Krist won the Democratic nomination and will take on incumbent GOP Governor Pete Ricketts in the fall. Ricketts is widely expected to win a second term.

U.S. Senate (Democratic primary): Lincoln City Councilwoman Jane Raybould wins Democratic Senate nomination in Nebraska. Sen. Fischer is not thought of as a prominent Democratic target this cycle in the Senate, but prior to her winning the seat was held by Democrats Ben Nelson and Bob Kerrey for over 20 years. The AP has already projected that Fischer has won the GOP primary for U.S. Senate in Nebraska. Raybould is hoping she can be the next Democratic senator from a state that Bernie Sanders won in the 2016 Democratic presidential primaries.

The Democratic race in Nebraska's 2nd Congressional District between former Rep. Brad Ashford and first-time candidate/non-profit executive Kara Eastman has not yet been projected, but election returns show a very tight race with the candidates within a percentage point of each other.

10:00 p.m. - AP calls GOP primary for Nebraska Gov. Pete Ricketts

According to the AP, Republican Gov. Pete Ricketts dominated Nebraska polls in his quest for a second term fending off a challenge from medical marijuana advocate candidate Krystal Gabel of Omaha.

9:48 p.m. - AP calls Penn. GOP Senate nomination for Barletta

The Associated Press has called the GOP Pennsylvania Senate nomination for Rep. Lou Barletta, a four-term congressman, and Trump supporter who also received a nod from the president.

He goes on to face Democratic Sen. Bob Casey in the fall, who according to AP, is one of roughly ten Democratic incumbents in that chamber facing re-election in states Trump won during the 2016 elections.

9:30 p.m. - More from voters in Pennsylvania

ABC News Stephanie Ramos and MaryAlice Parks trekked through the congressional districts ringing Philadelphia's suburban districts speaking with voters earlier in the day.

Democratic voters they spoke with told ABC News they are optimistic about the primaries leading into the midterms.

One voter in the 5th Congressional District said: “We feel it's time to take back our country, and take back our state and get the majority in Congress so that we can start moving things forward. The things that really matter to the people.”

But not everyone was so optimistic about how the midterms may turn out despite the turnout.

Another voter in that same district said: “I think the temperature is a little lower on the president right now. I think we have to keep up the pressure, I think we have to elect more democrats – especially women Democrats.”

One of those female Democrats on the ballot, Chrissy Houlihan, said women are willing to work across the aisle and compromise.

“To be the largest state in the country to have no women representatives in government, and I think that, I hope very much to be one of many people to break that trend," she said.

6:00 p.m. - More on the Idaho, Nebraska, and Oregon primaries

In Idaho, the primaries in both parties to succeed term-limited GOP Governor Butch Otter are competitive in this mountain west state that voted for Trump by more than 30 points in 2016.

The Democratic race is between state representative Paulette Jordan, who has embraced more progressive policy positions and would be the state’s first female governor and the nation’s first Native American governor, and businessman A.J. Balukoff, who ran unsuccessfully for the Democratic nomination for governor in 2014. The Republican race has been an expensive three-way battle between U.S. Rep. and House Freedom Caucus founder Raúl Labrador, Lieutenant Governor Brad Little, who has Governor Otter's endorsement, and businessman Tommy Ahlquist.

In Nebraska, the marquee race is in the state’s 2nd Congressional District, which Hillary Clinton narrowly lost to Donald Trump in the 2016 election. The race is between former Rep. Brad Ashford, who used to represent the district, and first-time candidate Kara Eastman, who has taken more progressive policy positions.

In Oregon, the race to watch will be the GOP gubernatorial primary to take on incumbent Democratic Governor Kate Brown. State Rep. Knute Buehler is the front-runner but has had to spend heavily on TV ads to fend off a crowded slate of primary challengers that includes wealthy businessman Sam Carpenter and former Navy Captain Greg Woolridge, who was once the commanding officer of the Blue Angels – the Navy’s precision aerobatic team.

6:00 p.m. - One candidate's quest to become Idaho’s first Native American governor

Paulette Jordan, a former Democratic Idaho House Representative who hails from the Coeur d’Alene tribe is hoping to advance her political position to become Idaho’s first Native American governor.

"I experienced the joys of self-sufficiency and developed a deep connection to the land," she says on her campaign website. "But I also felt the frustration and disappointment of my neighbors and relatives, many of whom struggled in our failing school system and our broken economy."

Jordan says her roots helped inspire her political aspirations. She grew up on a farm in northern Idaho where she developed a strong connection to the land and a desire to protect its natural resources.

Jordan attended the University of Washington where she discovered her love and passion for politics and grassroots activism. As a student, she worked on the Seattle City Council and the university’s administration representing her classmates. She also served as a city council member on the Coeur d'Alene Tribal Council.

In 2014, she ran for the Idaho House of Representatives and defeated an incumbent Republican. She was re-elected in 2016. In February, she announced her resignation in order to focus on Idaho’s upcoming governor race.

Idaho has a lengthy history of voting Republican.

In the 2016 presidential election primaries, President Trump dominated the state defeating Hillary Clinton by nearly 32 points.

Whites make up 93.3% of the population and Native Americans make up 1.8% according to the U.S. Census Bureau.

Throughout her tenure, Jordan has primarily pushed for education innovations, Medicaid expansion, and keeping public lands in the hands of its people. She says she will continue to fight for these issues if elected.

"Our vision is an Idaho in which every acre of our public land is protected and preserved for future generations," Jordan said on her campaign site. - Erica King

3:00 p.m. - "Pink wave surging."

ABC News' Cheyenne Haslett reports that Tuesday's primaries are especially significant because of the record number of women in the state running for Congress, according to Jennie Sweet-Cushman at the Pennsylvania Center for Women and Politics at Chatham University.

There are, by some estimates, 23 women on the ballot running for the U.S. House of Representatives. While there are no women listed as running for Senate, and one woman, Republican candidate Laura Ellsworth, is running for governor.

7:00 a.m. - Pennsylvania highlights slate of four primaries.

According to ABC News' John Verhovek and Adam Kelsey, the Pennsylvania Supreme Court's decision earlier this year to approve redrawing the state's congressional districts resulted in a number of competitive House races, and an influx of candidates from both parties have launched campaigns in the state's six open-seat races.

There are currently 10 Republicans and six Democrats in the state's congressional delegation. However, the congressional lines are more geographically compact under the new map, which could provide an opening for Democrats to flip seats that have traditionally leaned Republican.

6:00 a.m. - The Note: Pennsylvania's primary a test for Democratic women

In ABC News' "The Note", Rick Klein and MaryAlice Parks write that Democratic female candidates are off the sidelines. But that doesn’t mean they are players in the game – at least not yet.

If there’s going to be a “pink wave,” it basically has to start building in Pennsylvania, where primary elections are being held on Tuesday. There is perhaps no more important state to Democratic hopes to take over the House, and the state’s all-male – and 2-1 Republican – House delegation is virtually assured of looking a whole lot different in 2019.

More than 20 Democratic women are running, in 13 of the Keystone State’s 18 House districts. A few will almost certainly become members of Congress, and many will, of course, fall short.

One primary to watch closely for ramifications for the fall: the First Congressional District, in the suburbs north of Philadelphia.
