With high-profile defections in the Senate (Sen. Reid and Sen. Dodd), the FISA compromise looks like less of a sure thing than it did when it comfortably passed the House last week. There's still (probably) enough votes for cloture.

The Democratic Netroots have been furiously pressuring members of the Senate and have been critical of Barack Obama for reluctantly support it. Which leads me back to a question, really, about Nancy Pelosi. Did she support the FISA bill in part because she wanted to provide cover for Sen. Obama with the left flank of the party? As a former ranking member of the intelligence committee, she knows more about the subject than most of her colleagues, and her every public utterance has tended toward a very different view than the expressed intent of the compromise bill. What do you think?
