WOODSTOCK, Ga. — Former Arkansas Gov. Mike Huckabee travels the country in a bus adorned with his smiling face and the cover of his latest book. But the ordained Baptist minister and potential 2016 presidential candidate makes it clear that he’s interested in more than best-seller lists.

“I think everyone understands where this is headed,” Huckabee said after signing books in metro Atlanta. After all, he joked, he didn’t recently leave his own Fox News Channel show “because I want to spend Saturdays at home.”

No, Mike Huckabee wants to spend his time in the Oval Office.

The man who won the Iowa caucuses and seven other states in 2008 has reassembled key players from his first presidential campaign. They’re working at his not-for-profit organization, America Takes Action, poised to transition from exploring a run to a formal campaign. He’s spent months courting potential donors and mixing speaking engagements into his book tour. Huckabee, 59, told The Associated Press he expects to decide in April or May.

Along the way, he’s fine-tuned his pitch for aggressive foreign policy, economic populism and social-conservative orthodoxy, a mix designed to attract Republican primary voters as well as independents in a general election. But this time, he’s carefully ordered those priorities.
