Since we're talking about who should drop out and calling for "Superdelegates" to decide the Democratic primary RIGHT NOW, maybe Congress should just go ahead and convene the Electoral College and send McCain packing. Here's why:

National Polls (RCP Average):

Clinton v. McCain: Clinton 44.8%, McCain 45.8%
Obama v. McCain: Obama 44.6%, McCain 44.4%

Well within the margin of error. Clearly McCain has not made his case, despite the benefit of his party's incumbency, early coronation, the alleged weakness of his opponents, and the endorsement of sitting president George W. Bush.

Popular vote (Green Papers):

McCain: 7,441,267
Dem: 27,815,851 (Obama: 13,961,775, Clinton: 13,854,076)

Wow. Not too many ways you can spin these numbers. Clearly, McCain is toast and should drop out for the sake of unity, etc. etc.
