Time to shut up about Huckabee?

According to the Drudge Report, the Democrats have decided not to attack Mike Huckabee for his comments about quarantining HIV patients, believing Adam and Eve were two actual people, that God has been helping him in the polls, etc. Why? Because they feel he is so vulnerable on these points that he would be easy to take down in the general election. Apparently they'd love to see him win the nomination so they can crush him in November. I'm not entirely sure. "Do you want a president who believes the Earth is only 6000 years old?" is a question that seems likely to alienate people with even lightly-held religious beliefs.
