Via the Politico, I see that:
In an interview with WHO radio in Des Moines, Iowa, Huckabee would not discount the possibility of another presidential run — but added he would need evidence of a clear path to victory before jumping into the GOP race.
“I’m not ruling it out. And that’s not a yes, but it’s definitely not a no,” Huckabee told WHO’s Steve Deace.
“The honest answer is: I’m keeping it open as an option; I’m looking at whether or not there’s a pathway to victory,” he added. “As I’ve told several people, I’m not jumping into a pool when there’s no water in it.”
When Huckabee sought the presidency in 2008, he had everything to gain and little to lose. He was an unemployed former governor without much name recognition who entered the race with low expectations. By the end of the campaign, he had emerged as a political force, a national celebrity with a cult following, and he landed a TV show and wrote several books. Now, looking ahead to 2012, things are a lot different. He’s earning good money for the first time in his life and people listen to what he has to say. Were he to run, he’d have to give up his Fox show, deal with the daily grind of the campaign, and once again open himself to more scrutinity and attacks. He’ll have to go through the process of explaining controversial past statements and defending his record, especially when it comes to pardoning violent criminals. And after all of that, it may be hard for him to improve upon his performance anyway. If he decided not to run, he could keep his television show and lucrative career, avoid being the subject of attacks, and still influence the race. His endorsement would no doubt be highly sought after, especially before the Iowa caucuses. So his statement seems pretty candid to me. There’s nothing to gain from running again unless he’s convinced he has a good chance of winning.
