TechPresident has a good breakdown of the varying opinions on the left of the Senate healthcare bill on their blog today:

On the chance that you haven't been closely tracking the blow-by-blow, we present to you a quick guide to the players and the arguments they're making over whether the health care package emerging from the Senate's legislative process is something worth saving, or a botched mess deserving of a quick and merciless death.

If you haven't been glued to progressive blogs Firedoglake, AmericaBlog, DailyKos, and other blogs including Wash Post's Ezra Klein and The New Republic's Jonathan Cohn the way the way we have...here's your chance to play catch-up, should you so desire.
