The protests at the Town Hall meeting are not doing PR damage to the opponents of Obamacare; rather the opposite:
I confess, I would never have guessed that. And the fraction of independents who say that their sympathy is increased or unchanged is 73%, slightly higher than the overall average. While I share the protester's aims, I personally think that shouting down Congressman is both a violation of our civic duties, and terrible tactics. But apparently the rest of the country isn't so worried by it.
Update: The Obama White House seems to have tapped into whatever lake of Crazy Juice the Birthers are drinking from. White House spokesman Bill Burton apparently claimed that right-wingers are showing up at health care events dressed up as Hitler.
