I wasn't aware he'd stopped campaigning.
I'll call the election right now--Obama wins. The Dems give us Jimmy Carter, Jr, and the RINOs think they're not moderate enough (read: far enough left). Hell, they ran Obama's biggest fan against Obama last time, and like somebody already said, "All they've suggested so far is the group that lost to McCain last time around."
If they really wanted to do this fairly, Primary Day would be one the same day around the country. It wouldn't let New England pick our candidates.
