My concern is McCain loses the primary or sins reelection he will push for immigration reform. MCCain has to go. The Senate GOP memebrs need to tell Graham-nesty that if he even thinks about amnesty then they will do something serious. I am not sure what but something.
If McCain wins the primary and the general, he'll spend the next six years poking conservatives in the eye with a sharp stick at every opportunity.
If McCain loses the primary, he'll spend every waking minute over the next four months poking us in the eye. He could still create a lot of damage in a lame duck session...
