Ezra Klein discusses Kaiser's poll in aftermath of Mass special election, broken down by Brown voters, Coakley voters and non voters. Here is a detailed breakdown of the poll results.
Here is Kaiser's national January tracking poll, 42% for 41% against, 16% unsure. Among Dems, 64% favor; Repubs 76% opposed; independents, 41% favor/43% oppose. The more details they hear of the bills the more supportive they get. Thing people like the most are insurance market reforms; like the least, individual mandate. That is classic....because they go together. You can't do away with pre-existing conditions if you don't pull most everyone in.
