"I think the Lieberman skeptics are really on to something when they point out that in the Kondrackes and others there is this sense that for a well-liked-in-the-beltway senior pol like Lieberman to face a primary challenge is somehow a genuine threat to the foundations of the system. You'd think he was a life peer, if not an hereditary noble, suddenly yanked out of the House of Lords and forced to run for his seat like they do in the Commons."
