Now there is talk of Lieberman running for re-election as a Republican. Lieberman coyly told CNN he was "unlikely" to do so, but he didn't slam the door on the idea either. If those who see the senator as a DINO (Democrat in Name Only) get their way, they will chase Lieberman into the GOP's loving arms.
Where does it end? Look to the California Legislature -- a study in polar dysfunction. Republicans who reluctantly voted for tax hikes have faced recalls or lost leadership posts, while a Democrat who voted against Speaker Karen Bass on the state budget lost her Capitol office. The state's leaders can't balance the budget, but they sure can punish dissent.
GOP strategist Allan Hoffenblum figured he could count maybe four moderate lawmakers who would dare cross their party's dogma. Sacramento, he quipped, is "Disneyland for ideologues."
And if the folks at Moveon and Firedoglake have their way, Washington will follow.
