There won’t be an incumbent in 2016, but another variable remains in play. Were Huckabee to declare for the race, he’d have to give up his salary from Fox—$500,000 as of 2011—and many of his other income streams. He has called this “a big issue.” At one point, he jokes to me: “I want to be careful that I’m not announcing a candidacy here. Because that would be disastrous.”
If he decides to give it a go this time, Huckabee would have to give up his Fox News show once he took more serious steps to running, like forming an exploratory committee and raising money.
