Bush v Obama was 44/50. So, Huckabee squeaks by Bush by one. You would think that as unpopular as Bush was - approval in the 20's when he left office, a GOP candidate would be able to break the 50% barrier fairly easily, especially considering how far Obama has fallen the last 5 months - some 20 points or more.
I'm not saying it's bad news for Huckabee or Palin, just a little disappointing that neither can surge well past Bush.
Bush v Obama was 44/50 : -6
Huckabee v Obama was 45/46 : -1
Difference between Huckabee and Bush versus 0bama: 5%
