Prior to the election, Lieberman toyed with the idea of convening a group of senators to reach a tax cut compromise. He's put those plans aside for the moment, to let party leaders work it out.
"I think what I decided at least for the lame duck is that this is going to happen at a pay grade higher than mine," he said.
Now, before the lame duck session, Lieberman distinguished himself from the GOP by saying he had no interest in blocking middle-income tax cuts to force the Democrats' hand on tax cuts for upper income Americans. But the plan he's embracing -- a temporary extension of all cuts -- is as far as the GOP is willing to go, and basically punts this political fight a year or two into the future, when presidential politics will further complicate it.
