Hillary Clinton and Donald Trump are deadlocked in four battleground states, according to new NBC News/Wall Street Journal/Marist polls released Sunday.

The four states are Arizona, Georgia, Nevada and New Hampshire. In senate races, Republicans are leading these four states, though Nevada is within the margin of error.


Among likely voters in Arizona, Trump leads 42 percent to 41 percent, well within the margin of error of 3.8 percentage points. Clinton, however, leads among registered voters with 41 percent to 40 percent. There is a margin of error of 3.2 percentage points.

Republicans have won in every presidential election in Arizona since 2000. This year, Clinton's camp have been keeping an eye on the state, even announcing plans to purchase TV air time.

Though it’s a tight race between Clinton and Trump in Arizona, Republican incumbent Sen. John McCain is carrying the state with a 19-point lead against his Democratic challenger, Ann Kirkpatrick, 57 percent to 38 percent.

In Georgia, Trump leads by 3 points among likely voters, 46 percent to 43 percent. The margin of error is 3.9 percentage points. Among registered voters, Clinton and Trump are tied at 44 percent, with a margin of error of 3.2 percentage points.

Since 1996, the GOP has won Georgia. Like Arizona, though, Clinton's team is trying to turn the state blue. Her campaign also announced plans of purchasing TV air time in that state, too.

In the Senate race, Republicans are up. Incumbent GOP Sen. Johnny Isakson leads Democratc candidate Jim Barksdale, 53 percent to 38 percent.

Clinton takes the lead in Nevada by 1 point, with 45 percent to 44 percent among likely voters. There is a margin of error of 3.9 percentage points in that poll. Clinton's lead widens among registered voters, with 46 percent to 41 percent. There is a margin of error of 3.2 percentage points.

President Barack Obama carried Nevada in both 2008 and 2012.

For the Senate race, which has become a key state with Senate minority leader Harry Reid retiring, Republican Joe Heck takes the lead, with 47 percent to Democratic candidate Catherine Cortez Masto with 45 percent. Among registered voters, Cortez Masto is up 1 point, 46 percent to 45 percent.

In New Hampshire, Clinton is up 1 point on Trump among likely voters, with 42 percent to 41 percent. There is a margin of error of 3.6 percentage points. Among registered voters, Clinton and Trump are tied at 40 percent. There is a margin of error of 3.1 percentage points.

Obama won New Hampshire in both his elections.

Incumbent GOP Sen. Kelly Ayotte is leading her Democratic challenger, Gov. Maggie Hassan, in the Senate poll with 52 percent to 44 percent. Ayotte’s lead shrinks by 1 point among registered voters, 51 percent to 44 percent. The senate race in New Hampshire could likely determine which party takes control of the Senate.
