Webb vs Lieberman

It has puzzled me why the Left was so eager to get rid of Lieberman but so ready to embrace Webb. Don't get me wrong, I understand realpolitik, and the need to accept the good with the bad in some of your politicians in order to get the results you want, but the Democrats seemed ridiculous in their exhuberant defense of Webb. Had they not read his books? Did they not know his record? Sure, he is against the War, but he is against it because he does not think it is being fought ruthlessly enough. I think we can say he is in the "Rubble don't cause trouble" school of thought. Seems hard to reconcile him with the Cindy Sheehan wing of the Democrat party, but I guess since he didn't vote to authorize the War, and since he was running against Allen, well, in that case, Webb is ok. I suspect the the Dems will rue the day they voted in another member of the Lieberman caucus.
