"Singing a different tune?"
Nearly everyone that has panned the Huckabee surge is doing so on the same general principle. "Yeah he's great on the social issues, but taxes under his watch in Arkansas went up 47%."
Which is true - even if it still kept Arkansas as the state with one of the lowest property tax rates in the nation.
Now the ultimate Mr. Anti-Tax is telling voters they should trust Huckabee's conversion on tax policy. (As many would also intimate that should be done with Romney's abortion position...)
I say it's fair in both circumstances...
