Huckabee as Governor of Arkansas raised taxes, and gave in-state tuition to illegal aliens at state universities. Huckabee also supported Cap-and Trade like Romney did (but now Romney claims he is against it for now).
It is sad that Romney is the best we can do.
If you are going after a previous record, then Romney is a far worse.
What Huckabee has done in the past pales in comparison to Romney's socialist healthcare disaster... which was a blueprint for Obama care.
Also, Romney was at one time pro-choice I believe.
If you are going after the candidates current platform... then its still a hands down win for Huckabee. Everything from Taxes, to Marriage, to Islam, to Israel. Sometimes I think he even listens to Chaim.
Yes, he is STILL not conservative enough... but of the lot... he is the most conservative and is an excellent debater.
