It hasn’t been the best week, and with the Iraq Study Group apparently poised to release its eagerly awaited plan for surrender later today, things are unlikely to get better anytime soon. So, before we get to the serious stuff, let’s cling to one piece of positive news.

Yesterday, Joe Lieberman refused to rule out the idea of caucusing with the Republicans in the Senate. As I typed that sentence and prepared to hit the “publish” button, I could sense veins popping across the progressive blogosphere. The AP reports:

Senator Joseph I. Lieberman of Connecticut said yesterday that he will caucus with Senate Democrats in the new Congress, but he would not rule out switching to the Republican caucus if he starts to feel uncomfortable among Democrats.

One can only wonder what kind of things would make Lieberman uncomfortable serving the Democratic Party. Perhaps something like a Majority Leader Murtha might do the trick.

I eagerly await the reaction of Markos Moulitsas to this news. Were it not for Markos’ ministrations, Lieberman’s ongoing loyalty to the Democratic Party would be much less of a question mark. Nonetheless, I expect Markos’ commentary to be colorfully indignant while betraying no sense of the potential damage he has wrought.
