Barack Obama appears to be enjoying a bump in the New Hampshire polls after his victory in the Iowa Democratic caucuses.

The Illinois senator had 41 percent support, up from 32 percent in mid-December, in a new USA Today/Gallup poll.

Sen. Hillary Clinton, of New York, slipped to 28 percent from 32 percent in the same time period. Former North Carolina Sen. John Edwards had 19 percent, New Mexico Gov. Bill Richardson had 6 percent, and no other candidate had 3 percent.

On the Republican side, John McCain had 34 percent, up from 27 percent in mid-December, while Mitt Romney had 30 percent, down from 34 percent.

Former Arkansas Gov. Mike Huckabee was third with 13 percent, while Rep. Ron Paul of Texas and former New York Mayor Rudy Giuliani were tied at 8 percent. No other candidate, including former Tennessee Sen. Fred Thompson, who conceded Sunday he was focusing on South Carolina rather than New Hampshire, was above 3 percent.

Both surveys had a margin of error of 4.4 percentage points, a small enough gap to consider the GOP race tied.

While the Iowa results influenced the demeanor of the candidates in a campaign shortened to five days by this year's compacted election calendar, New Hampshire residents have a history of keeping their own counsel in their first-in-the-nation primary.

"Undeclareds" make up the majority of registered voters in the state, and those independents are free to vote in either primary on Tuesday. Romney aides hoped for a surge in favor of Obama, denying McCain the independent votes that catapulted him past Bush in 2000.
