Nate Silver shows that most of the individual parts of health insurance reform are very popular:

What we see is that most individual components of the bill are popular -- in some cases, quite popular. But awareness lags behind. Only 61 percent are aware that the bill bans denials of coverage for pre-existing conditions. Only 42 percent know that it bans lifetime coverage limits. Only 58 percent are aware that it set up insurance exchanges. Just 44 percent know that it closes the Medicare donut hole -- and so on and so forth.
