So much, then, for Mr. Obama’s dream of moving beyond divisive politics. The truth is that the factors that made politics so ugly in the Clinton years — the paranoia of a significant minority of Americans and the cynical willingness of leading Republicans to cater to that paranoia — are as strong as ever. In fact, the situation may be even worse than it was in the 1990s because the collapse of the Bush administration has left the G.O.P. with no real leaders other than Rush Limbaugh.

The question now is how Mr. Obama will deal with the death of his postpartisan dream.

So far, at least, the Obama administration’s response to the outpouring of hate on the right has had a deer-in-the-headlights quality. It’s as if officials still can’t wrap their minds around the fact that things like this can happen to people who aren’t named Clinton, as if they keep expecting the nonsense to just go away…

What’s still missing, however, is a sense of passion and outrage — passion for the goal of ensuring that every American gets the health care he or she needs, outrage at the lies and fear-mongering that are being used to block that goal.
