Poll: Obama up big in swing-state New Hampshire

Obama leads with 53 percent over Romney at 41 percent. Romney led by 2 percent in the same poll conducted in July.

Romney launched his presidential bid and officially kicked off his general election campaign in New Hampshire. He also owns a vacation house and maintains close ties to the Granite State, which is near his home state of Massachusetts, where he served as governor.

{mosads}New Hampshire is one of 12 battleground states that will be critical in determining the outcome of the 2012 election, and while Romney has overtaken Obama in a number of recent national polls, his standing in New Hampshire has deteriorated.

In July, Romney had a slightly positive favorability rating in New Hampshire, at 43 percent approval, 42 percent disapproval. He’s now underwater at 40 percent approval and 54 percent disapproval.

Obama has gone from 46 percent approval and 49 percent disapproval last July to 52 percent approval and 45 percent disapproval in the state.

A CBS News-New York Times poll released on Monday surprisingly showed Romney with a slight advantage among women nationally, but Obama trounces Romney with female voters in New Hampshire, 58 to 35.

Young voters also helped buoy Obama in New Hampshire — he leads Romney by 30 percent among those under the age of 30.

Adding freshman New Hampshire Sen. Kelly Ayotte (R) to the Romney ticket gives Romney a slight bump, but he would still trail Obama 52 to 42.

The PPP survey of 1,163 New Hampshire voters was conducted between May 10-13 and has a 3 percent margin of error.
