Victor Davis Hanson sums up the Dems rather nicely:

But with the present-day Democrats, they apparently must be careful that at any given second a Democratic Senator might go off and compare our troops to terrorists (Kerry), Pol Pot (Durbin), or Saddam’s jailers (Kennedy), or perhaps suggest Iraq was better off under the Husseins (Rockefeller). The result is an addiction to dissimulation, a constant paranoia that without warning someone will say what they feel, and thereby reveal to the American people just how far this bunch has strayed from Harry Truman, Henry Jackson, and JFK—and how radically they have become enthralled with the various victim industries, academia, Hollywood, and the fringe of Michael Moore, Cindy Sheehan, and the Daily Kos.
