You didn't read the first sentence of this thread. It says:
“Actually, the real scoop is that Huckabee has crawled to within one thin point of The One at 46/45.”
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.
