"You hear all the stuff about him cutting taxes for the rich, and we in the middle class are going to get stuck paying for everything like we usually do," said Leighton, 56, who isn't registered with either political party.
New Hampshire, where undeclared voters outnumber either Republicans or Democrats, had long been considered safe Republican ground until Bill Clinton won it in 1992 and again in 1996. George W. Bush narrowly prevailed in 2000, but in the next election, New Hampshire was the only state to reject Bush after voting for him four years earlier.
Obama won the state in 2008, but Republicans made huge gains in 2010, retaking the state's two congressional seats and winning commanding majorities in the state Legislature. According to exit polls, Obama had a slight advantage among the more than four in 10 who called themselves independents Tuesday, though his support among that group dropped from 2008.
