Voters in Florida, Arizona, and Oklahoma head to the polls tonight, and Breitbart News will have live updates throughout the evening.

In Florida, Rep. Ron DeSantis, whom President Donald Trump endorsed, and Adam Putnam will seek the GOP’s gubernatorial nomination in a contest that could again show how important Trump’s endorsement is in a GOP primary.

In Arizona, days after Sen. John McCain’s passing, Martha McSally, Kelli Ward, and Joe Arpaio are seeking to win the GOP Senate nomination for retiring Sen. Jeff Flake’s seat.

Stay tuned to Breitbart News for live updates of all the important races on both sides of the aisle. All times eastern.

Martha McSally, running in the Arizona Primary for U.S. Senate, was endorsed by rejected Senator Jeff Flake….and turned it down – a first!

12:35 AM: Impeachment activist Tom Steyer and his group spent nearly $1.5 million to help Gillum, and they are celebrating his win. Gillum called for Trump to be impeached in December of 2017, saying “Donald Trump should be impeached now.”

11:45 PM: McSally asks for moment of silence for McCain:

Martha McSally, projected winner in Arizona's GOP Senate primary: "Senator McCain was an American hero. He paid an unfathomable price for our freedom, and upon returning home continued to serve with conviction, honor and sacrifice his whole life." https://t.co/SuHqnQa2BL pic.twitter.com/hiNHlxTQ5O — This Week (@ThisWeekABC) August 29, 2018

Clearly emotional. McSally says she is the Republican nominee. Asks for moment of silence for John McCain. Calls @kyrstensinema a talker, protestor, and career politician pic.twitter.com/gvy4kgrEEg — Nick VinZant (@NickVinZant) August 29, 2018

10:30 PM: More Republicans voted than Democrats in Florida:

With 99% of precincts reporting in Florida, about 120,000 more Republicans turned out to vote for governor than Democrats. We'll see how many of the ~700k Repub voters who didn't vote for Trump's candidate today do so in Nov. And Dems now fielding 1st black nominee in FL history. https://t.co/ffFxLV94XZ — Jory Rand (@ABC7Jory) August 29, 2018

9:45 PM: Stitt wins OK GOP gubernatorial nomination:

9:25 PM: Oklahoma:

Kevin Stitt told me he thought turning someone’s last name into a curse word is a new low. He thinks the ad actually backfired and led more people to support him 🏻‍♀️ https://t.co/GmBqnqssSl — Caroline Vandergriff (@c_vandergriff) August 29, 2018

9:05 PM: In Oklahoma, Kevin Stitt leads Mick Cornett 55%-45% with 47% reporting.

The way this Governor runoff goes will be a good indication of where Oklahoma stands politically. Stitt has strongly aligned himself with Trump and electing outsiders into office. — Mireya Garcia (@mireya_g) August 29, 2018

8:50 PM: None other than Donna Shalala, the former head of the Clinton Foundation, is projected to take on Maria Elvira Salazar for retiring Rep. Ileana Ros-Lehtinen’s (R-FL) seat.

8:40 PM: Putnam concedes, and with nearly 80% of the vote in in Florida’s Dem. gubernatorial primary, Gillum leads Graham 33%-32%:

Chants of "Andrew!" "Gillum!" now echoing in the ballroom, and screams as MSNBC shows them tied. @AndrewGillum's uncle Vincent Sams tells me, eagerly, "We're going to win." Votes from parts of the Panhandle — Graham country — still need to be counted — Elizabeth Koh (@elizabethrkoh) August 29, 2018

Governor Rick Scott officially wins the GOP Senate nomination. Scott, who leads by 6 points in the latest poll and has a slight lead in the RealClearPolitics average, will take on incumbent Sen. Bill Nelson (D-FL). Fox News has called the GOP gubernatorial primary for DeSantis–a huge win for Trump, whose endorsement propelled DeSantis into the lead.

7:20 PM: DeSantis (R) and Graham (D) with early leads in their respective gubernatorial primaries.

Early-voting results have DeSantis with healthy lead on Putnam in Orange, Osceola. — Scott Maxwell (@Scott_Maxwell) August 28, 2018

7:15 PM: Democrats are trying to take back Florida’s governorship for the first time since 1994 and Tallahassee Mayor Andrew Gillum has an interesting mix of endorsements from the left as he makes a charge against frontrunner Gwen Graham, the daughter of the late Florida Senator. Gillum has been endorsed by Sen. Bernie Sanders (I-VT), who rails against billionaires influencing politics, and Julian Castro. But billionaires George Soros and Tom Steyer have been pouring in hundreds of thousands of dollars to boost the left-wing challenger. Celebrities like Diddy have also made last-minute endorsements.
