He said Romney's message boils down to "Don't pay too much attention to our solutions are, just be disappointed, and look at me: I look like a president, and I talk like one, and I'm telling it's going to be all right if you elect me," he said.
A WMUR Granite State Poll released Saturday showed Obama and Romney tied in New Hampshire, which backed Obama in 2008 but has been highly contested this election cycle.
Making his closing case to voters Sunday in Des Moines, Iowa, Romney also pledged, if elected, to work with Democrats to restore the American dream and bring the economy roaring back to life.
"We're Americans. We can do anything," Romney said. "The only thing that stands between us and some of the best years we can imagine is a lack of leadership — and that's why we have elections."
Romney's campaign spokesman, Michael Levoff, said re-electing Obama will result in four more years of stagnation.
"The people of New Hampshire, along with the rest of America, will choose Governor Romney's optimistic vision for our country's future and will vote for real change so he can get our country back on the right track," he said.
