Sen. Bernie Sanders (I-VT) is making the loudest filibuster threats in the Senate right now, vowing to do all he can to block President Obama's tax cut compromise.
Here's how: "Find a handful of Republicans who are willing to vote no on this agreement and then come back and come up with a proposal that is much stronger and much fairer," he told reporters today.
"What I'm saying as a progressive should appeal to conservatives all over this country," Sanders added. "I think we have a winnable fight here. I think the American people are with us and I intend to do everything that I can to defeat this proposal."
No doubt a few Republicans will break from the GOP, but it will take a full 41 members to guarantee that the plan goes down. So far, Sanders won't say if he has any allies on the right.
