Mike Huckabee is heading to Iowa next week, his third trip since winning the state's caucuses last January.

Next Wednesday, the former Arkansas governor will speak at the Iowa Association of Business and Industry's annual convention in Okoboji. The subject: climate change. Later, he keynotes to the "Leadership at the Lakes" event in Arnold's Park, organized by Bob Vander Plaats, a potential candidate for governor next year.

Yes, it's already that time. Sen. John Ensign was there last week.
