I recommend Charles Krauthammer's article The Electorate vs. Obama's Agenda in yesterday's Washington Post. Although hubris and arrogance seem to permeate Washington politics in both parties, it is particularly noticeable these days in the liberals, probably because they are in power at the moment.
One can only wonder, for example, at the arrogance of Speaker Pelosi, determined to push through the health bill irrespective of the clear message from polls and recent by-elections that the majority of the electorate doesn't want it. Well, these things have a way of sorting themselves out at the next election.
