Larison has some sharp analysis of the Brown win.
Democrats have convinced themselves for years that the public overwhelmingly favors “health care reform,” which they pretty readily identify with their own ideas on what that reform should be, and now Republicans have convinced themselves that the public will not stand for passage of a health care bill. My guess is that both have been wrong in different ways, but the GOP is probably misreading the situation even worse than the Democrats. Republicans are betting heavily that a bill that is passed this year but which will not take effect for several more years is going to precipitate a massive public backlash in their favor. Democrats are assuming that the voters who handed them 14 Senate and 50+ House seats over the last two elections are not going to throw them out of power for doing more or less what they said they would do. Whose bet seems smarter?
