President Obama and Mitt Romney remained locked in tight contests in Nevada and North Carolina, but the incumbent leads by seven points in New Hampshire, according to new swing state polls from NBC News and Marist College.
The polls show Obama with a two-point edge in both Nevada and North Carolina, 49 percent to 47 percent in the former and 48 percent to 46 percent in the latter -- both within the margin of error. In New Hampshire, he leads 51 percent to 44 percent.
The polls are slightly better for Romney than other recent polling -- particularly in Nevada and North Carolina. But they are pretty much on par with previous surveys in these states and don't show much movement.
In a key Senate race in Nevada, the poll shows Sen. Dean Heller (R-Nev.) leading Rep. Shelley Berkley (D) by six points, 49 percent to 43 percent. Republicans likely need to hold the seat if they are going to have a shot at the Senate majority.
And in arguably the top two governors races in the country -- in New Hampshire and North Carolina -- the numbers are mixed. Democrat Maggie Hassan and Republican Ovide Lamontagne are neck-and-neck in New Hampshire, with Hassan at 47 percent and Lamontagne at 45 percent. In North Carolina, the poll shows Republican Pat McCrory opening a 13-point lead on Democrat Walter Dalton. McCrory is favored to succeed retiring Gov. Bev Perdue (D).
