The "endorsement" amounted to a choice of the lesser of three evils. At the time, the choices were John McCain, Mitt Romney and Mike Huckabee.
Huckabee had the fewest problems. He also had the fewest achievements.
True, the first choice was Thompson.
I don't think the original poster was looking to see if Huckabee had enough "achievements" to speak at a Southern Baptist event.
