Now that Chris Dodd and Russ Feingold have announced that they will attempt to filibuster the FISA faux “compromise” sent over from the House, Barack Obama has another very difficult choice to make with really no good answer.

Presumably, he will vote for Harry Reid’s amendment stripping retroactive telecom immunity from the bill. The Republicans will filibuster it. Then Reid, showing the spinelessness that has distinguished his term as Majority Leader, will pull the amendment. Then Dodd and Feingold will try to stop ending debate.

What does Obama do?

If he votes to filibuster, then he looks foolish because just last week he supported the House bill, with a weak statement that was really beneath him. If he does this, then he’s “flip-flopped in four days.” (Not as agile as McCain, of course, but that never matters according to the Beltway press.). But if Obama votes to end debate, then he plays along with Republicans and further infuriates the base (and by the way all those who believe in accountability). Either way, he does not look good.

I suspect he will vote to end debate. And that will leave a very bad taste in the mouths of many Democrats. One might even call it “bitter.”
