Sen. Kent Conrad and Sen. Joe Lieberman announcing that they are not running for re-election in 2012, on the same day? Boy, some days are indeed better than others!
For the untold damage they have done to this country in the last couple of years, I say: good riddance, both of them! All you need to do is check out the comments at the bottom of each article to see that my sentiments are largely those shared by other progressives.
On the other hand, as a couple of folks said in their comments, two bad things are going to happen: 1) We won't get the satisfaction of voting either one out of office. 2) There is going to be a fire sale on a few Senate votes: Lieberman and Conrad's votes are now up for grabs for the highest bidder (not that they have not always been).
The one thing I am not too worried about is losing their seats to Republicans. They were not ours to begin with. (Kent Conrad has been mentioned many times on this blog, for his corrupt pussyfooting on and/or active obstruction against meaningful health care reform. Sen. Lieberman has too. You might particularly enjoy the two posts in which Stephen Colbert skewers the old idiot.)
