The former Arkansas governor frequently leads in national polls of Republican primary voters and, with Haley Barbour not running, would be the only candidate with a strong claim to the Southern voters that form the backbone of the party. Despite being significantly outspent in 2008, he won an upset victory in the Iowa caucuses and won large shares of the vote in a number of other states, including South Carolina.

Huckabee's top advisor, Ed Rollins, told ABC News that he does not believe he Huckabee will enter the race. But he added that "if he announced tomorrow night, on Monday I could push the button and the campaign would start to unfold."

In his e-mail, Huckabee said that he had only come to his final decision, whatever it may be, at the last minute.

"It was this afternoon before I could even get word to all of my own children and even now, the executive producer of my show and the staff and crew of the show don't know and won't until I actually do the final preparation literally minutes before I share the decision live Saturday night," he wrote.
