Another pundit sees fit to blame the "McGovernites" for the defeat of St. Joseph. Thomas Edsall writes in the New Republic:

In a quick and dirty analysis of the difference between the Lamont and Lieberman voters based on income, education, and other demographic data from across Connecticut, Ken Strasma of Strategic Telemetry found that Lamont's strongest support came from areas with high housing values, voters with college or graduate degrees, and parents with children in private schools. Lieberman's votes, in contrast, came from the cities, renters, blue-collar and service-sector workers, and those receiving Social Security benefits.

There is nothing wrong with upscale liberals or downscale renters; a vote is a vote. The problem for the Democrats is (and has been for more than a quarter century) that liberal elites are disproportionately powerful in primaries--where they turn out in much higher numbers--and in the operations of the party itself. In presidential campaigns, these voters have nominated a succession of losers, including George McGovern, Michael Dukakis and John Kerry. The power of this wing of the party is easy to see in battles against Republican Supreme Court nominees, when Democratic opposition concentrates on such issues as abortion and sexual privacy to the virtual exclusion of questions of business versus labor, tort law, and the power of the state to regulate corporate activity.

With all due respect, I'm not sure that's an accurate breakdown of the votes. The exit poll done by CBS/New York Times showed almost no divergence in the vote based on income; Lieberman barely won among those who made less than $50k, and Lamont barely won above that total. Lamont did win a clear majority of votes, according to the exit poll, among those two "elitist" voting blocs, union members and African-Americans. Lieberman won among Catholic and Jewish voters, and among voters who never attended college. There was no gender gap to speak of. In short, this was a fairly typical intramural battle between two Democrats, and not some bellweather repudiation by Brie-snorting elites against the working class.
