Picking a Winner?

John Hinderaker points to one important reason why conservatives may bite the bullet and cast a vote for McCain in 2008:

But there's no denying that one reason lots of conservatives--like me--wouldn't mind seeing McCain as the Republican nominee in '08 is that no Democrat currently on the scene has the chance of a snowball in a warm place of beating him. Evidence: Rasmussen Reports currently shows McCain leading Hillary Clinton 44% to 43% in Massachusetts.
