The filing period began March 3, the day before Huckabee withdrew from the presidential race, and ends Monday.

In a mid-February breakfast with reporters, Huckabee joked, “There’s a greater chance that I would dye my hair green, cover my body with tattoos and go on a rock tour with Amy Winehouse.”

Huckabee repeated that joke Friday, adding: “That was a pretty apt description of my total lack of interest in running for the Senate.”

The former governor said he is trying to figure out “what's next,” but he is enjoying his return to non-campaign life, saying he has slept in his own bed two nights in a row and his dogs are starting to recognize him again.

Huckabee has been mentioned by some as a perfect fit for the Republican ticket, running with Sen. John McCain (Ariz.).

But the former governor said Friday that he doesn’t “have any indication that I’m on Senator McCain’s list.”

“The honest answer is I don’t get to be interested in it,” Huckabee said. “That’s Senator McCain’s decision.”

For the immediate future, Huckabee said he has to start making some money. The former governor has a standing deal with Premier Motivational Speakers Bureaus, and he said he has already lined up some paid speaking jobs.

“I think a lot of people thought I was sitting around with a Plan B in my pocket,” Huckabee said. “But the truth is I never thought about stopping.”

The former governor significantly raised his national profile with his presidential run. After spending most of 2007 branded by political observers as a quixotic also-ran, Huckabee shocked much of the political world by winning the Iowa caucuses on a shoe-string budget.

Huckabee continued piling up wins in conservative states, and he was the last major Republican candidate running against McCain until he dropped out Tuesday night.
