Healthcare Reform, Up or Down? Deeming or Redeeming?

So what does it mean to the left if the healthcare reform bill passes the House this weekend? Now that he's come around (along with Dennis Kucinich), Bob likens the bill to losing his virginity. It's not such a big deal after all! And the day after the vote, he wants the fixes to begin. What is this "deeming" procedure anyway? Is it worth risking a Constitutional challenge? A little bit about financial reform and what is a principled position – plus the contention that liberals will always pass a Democratic bill, no matter what. (Lawrence O'Donnell sits in for Matt Miller.)
