The gap between the right of the Republican party, which is providing the angriest critics of the reforms, and the left of the Democratic party, which thinks the proposals too timid, is unbridgeable. These groups do not merely disagree. They despise each other. Their differences are only secondarily about policy. They hold each other's values in contempt.
These snarling extremes are nonetheless somewhat alike. They have an equal and opposite penchant for conspiracy theories. Almost a third of Republicans, according to a recent poll, believe the unsupported story that Mr Obama was not born in the US (in which case he would be disqualified from serving as president). But remember that more than a third of Democrats subscribe to the even more outlandish theory that the Bush administration knew about the attacks of September 2001 in advance.
