Democrats hope to make Joe Barton really sorry.
Also in Slate, Michael Newman describes BP chief Tony Hayward's dodgy testimony.
By the end of the day David Plouffe, Obama's campaign manager in 2008, had sent an e-mail to millions of Obama's supporters asking them to sign an "open letter" that would send a message to Barton to show "him and other Republicans that they weren't elected to defend big oil." Even if people sign on to the effort, it's not a letter that Plouffe will ever send. The reality is there's not a single thing about Joe Barton's behavior they'd like to change.
