Huckabee is a liberal tax raiser and a liar who smears others (after saying he didn’t hve any intention of doing so), lies about other people’s records (just like McCain), and can’t win this race. He’s fundamentally dishonest.
I can’t imagine why he’s staying in, unless it’s to split conservative votes, ensuring McCain’s victory and getting the #2 spot on McCain’s ticket.
Splitting the conservative vote and ensuring a McCain victory is the reason.
