Democrats are salivating over the far-fetched idea that Republican Senator John McCain will accept the number two position on their presidential ticket. McCain disagrees with the prevailing stances among Democrats on tax cuts, spending, national defense, gay marriage, affirmative action, socialized medicine, and dozens of other issues. Amazingly, there's just one sticking point.

"Senator McCain would not have to leave his party," former Senator Bob Kerrey told the New York Times. "He could remain a Republican, would be given some authority over selection of cabinet people. The only thing he would have to do is say, 'I'm not going to appoint any judges who would overturn Roe v. Wade.'"

That's all McCain would have to do? Remind me: What party has the litmus test on abortion?
