If Boehner does anything other than say, 'Yeah, we're not coming back for a speech. You have fun, though.', he's a fool. There's *nothing* to be gained by doing this. Obama can flap his gums in the Oval Office. He doesn't need a joint session of Congress.
All Obama's going to do is say, "Here's my mega-bill. Don't read it. Just vote on it, right now. Pass it right now, or you hate babies, grandma, kittens, and Jesus."
