Read the full Rasmussen Reports Iowa poll and national tracking poll

Rasmussen’s latest survey shows Mike Huckabee running far ahead in Iowa, leading Mitt Romney by 39 percent to 23 percent, with everyone else in single digits. Huckabee gets a huge boost from Evangelicals – drawing 62 percent of their support. Fifty-six percent of likely caucus-goers say they will not change their mind before January 3.

Nationally, Huckabee is in a statistical dead heat with Rudy Giuliani, 22 percent to 21 percent. Romney polls at 14 percent; Fred Thompson at 12 percent, John McCain at 9 percent and Ron Paul at 5 percent. The Rasmussen poll squares with a CNN/Opinion Research survey from Monday that put Giuliani at 24 percent and Huckabee at 22 percent, well within the poll’s 5 point margin of error.
