Governor Mike Huckabee continues to ride the wave of momentum after his convincing Iowa Caucus win last week as he tops all Republicans in a new national USA Today / Gallup poll.  Huckabee has risen by nine points in the poll in the last month and Mitt Romney has dropped to fifth place in the national poll.

Republican Mike Huckabee and Democrat Barack Obama -- both winners in last week's Iowa caucuses -- have gained support at the national level among those who identify with their respective parties. Huckabee now has a 5-percentage point advantage in the Republican race nationally, while Obama is tied with Hillary Clinton.

These results are from the latest USA Today/Gallup poll of national adults, conducted Jan. 4-6, 2008. All interviews were conducted following Huckabee's and Obama's wins in Iowa last Thursday night. Results from Tuesday's New Hampshire primary may produce still further changes in the national standing of the candidates.

Among Republicans, Huckabee has jumped from 16% of the vote in December 2007 to 25% as of this polling. Coupled with the loss of support for former front-runner Rudy Giuliani, Huckabee is now the leader among Republicans nationally, with a 5-point lead over Giuliani and 6-point lead over John McCain (who has gained 5 points since December). Mitt Romney, after failing to win in Iowa, is now in fifth place nationally with just 9% of the vote, which is his lowest percentage since early October.
