Only in comparison to those so far to the Left that they almost fall off the edge of the planet.
My biggest hope is that Lieberman will get disgusted, and switch.
Won't happen. Liberman is a Democrat first, last and always even though he ran as an independent. He's also one of the professional class of politicians that infest our state and federal legislatures these days. The fact that he chose to do run as an independent instead of going into private life after the primary he lost says all you need to know about him. He ain't gonna willingly give up power now that the Dems are in the majority.
Ah, but Lieberman wouldn't necessarily have to give up his power. He's made it clear that he's "disappointed" in how the Dems treated him. He's staying with the Dems so he can keep his seniority (power). But the GOP could easily vote to let him keep his seniority if he switches.
He's out of step with the far Left that have control of the Dems now. I lost respect for him when he sold out to run with Gore, but I don't think he will go along totally with the Marxist Dems.
Seniority is the issue for him.
