Donald Trump and Hillary Clinton are tied in four battleground states, according to an NBC News/Wall Street Journal/Marist poll released Monday.
In Arizona, Trump leads Clinton by a razor-thin margin of 42 percent to 41 percent among likely voters. John McCain won his home state in 2008 and Mitt Romney won it in 2012.
The survey found that Trump leads Clinton by 3 percentage points in Georgia -- 46 percent to 43 percent -- among likely voters. McCain and Romney won the state in the last two presidential elections.
Clinton narrowly leads Trump, meanwhile, in Nevada, 45 percent to 44 percent among likely voters. She also leads Trump by the same margin in New Hampshire, 42 percent to 41 percent. President Obama won both states in 2008 and 2012.
The poll also measured support in the states’ key Senate contests. In Arizona, McCain leads Democratic challenger Ann Kirkpatrick by 19 percentage points. In Georgia, incumbent GOP Sen. Johnny Isakson leads Democratic Jim Barksdale by 15 percentage points. In Nevada, Republican Joe Heck leads Democrat Catherine Cortez, 47 percent to 45 percent in the race to fill Harry Reid’s Senate seat after he retires. In New Hampshire, incumbent GOP Sen. Kelly Ayotte leads Democratic challenger Maggie Hassan 52 percent to 44 percent.
The CBS News battleground tracker shows Clinton leading Trump only by 1 percentage point -- 43 percent to 42 percent -- in a set of 13 battleground states.
The poll surveyed between 913 and 987 voters in each state between Sept. 6 and 8 with a margin of error of about 3 or 4 percentage points.
