There's been virtually no change in public opinion about the health care bill since its passage. This month we find 43% of voters express support for it and 49% are opposed. Immediately before the vote in March the numbers were 45% favoring it to 49% in opposition.
Our polling since President Obama signed the bill into law has found support every month in the 43-45% range and opposition at 49 or 50%.
The numbers on health care did peak at the end, so even though they haven't improved since March the current level of support does represent a higher mark than we saw throughout most of the the debate on the bill. Support was stuck in the 36-40% range from November through February.
There's probably not going to be a big shift in public opinion on the health care bill until folks really start feeling it affect them one way or another.
