Hitchcock couldn’t do it any better. This one’s not ending until Ted Stevens and Robert Byrd are hanging off the side of Mt. Rushmore.

The guilty party’s got to ‘fess up soon. With every suspect who’s eliminated, his/her shamelessness at not having come forward sooner looks that much worse.

Update: If it does turn out to be Stevens, will he blame the Internet “tubes” for having led to his undoing?

Update: Up to 74 now. Ace thinks Byrd is the prime suspect.

Update: Stabenow denies it. Up to79.
