Wonder if Joe Wilson has an alibi: The search continues for the person who hollered "baby killer" at pro-lifer Bart Stupak last night as he urged Democrats to vote down a bill-killing Republican amendment on the issue.

The guilty party had "a southern accent," he says, but no one is naming names. "The people who know won't give it up."
