I don't see a poll on passage....gladly link to it if you point it out. They had a poll that said 54% opposed to passage....gallup said 49% oppose, 40% for. Interesting to see if Rasmussen also finds a switch. Here is a poll aggregator http://www.pollster.com/polls/us/healthplan.phpbut gallup appears to be the only one that is totally after the fact at this point.
I did not see a poll on passage. I did see an article that seemed to suggest a switch. A switch would not be surpirsing. I would imagine most people are just glad that there is a result one way or the other. Although I'm sure this is just the beginning. (read Rainmaker). I know that Rasmussen was the most accurate during the election, but I don't know if that lends more validity to him across the board.
