Two things might hurt the governor with Republicans: He's the second man from Hope to hold serious aspirations for the presidency (the first was, of course, Bill Clinton). The other? He's the official Republican pick of the Daily Kos.And don't forget that Sharon Cobb has said some kind things about him.
Also, Bill Hobbs (over at elephantbiz.com) has a great commentary on criticisms (from some Conservative quarters) of Mike Huckabee's decision to raise a gas tax to pay for road improvements in Arkansas. Obviously, some taxes are necessary; providing roads and defense are the two most legitimate governmental services; and it is very desirable and Conservative--in my estimation, to designate tax revenues for a specific purpose. Characterizing Huckabee as a taxandspendthrift on this basis? That dog won't hunt.
