Look, people, opposition to Lieberman isn't just about the Iraq war. It's about him "compromising" Democratic principles when he didn't have to, it's about selling out women, it's about thinking "bipartisanship" involves selling our your party so that Tim Russert will pat you on the head for your bravery, it's about dishonesty on things like the Bankruptcy Bill, and now it's about his contempt for the Democratic voters in his own state. And, yes, it's about the fact that the senator has indeed "lost the plot" on the Iraq war.
The Iraq war is more than enough, not simply for his initial support but for his subsequent slam on people who dared criticize Bush over it, but there are so many reasons to oppose Joe.
No need to choose just one.
I'm a very lucky person with every allergy known to man but still happy to be enjoying a wonderful life living in the best place in the world!
