Update: NChrissieB, identifying herself as a former criminal defense appellate attorney who focused on constitutional issues writes this at DailyKos:
A Pragmatist's View on FISA. I found it instructive.
MoveOn's campaign to hold Obama accountable. Obama campaign phone: (866) 675-2008
Glenn Greenwald's piece on Salon this Saturday provides I think a good overview of how we might interpret Obama's support for the FISA "compromise".
This is a seriously bad decision Obama has made, no matter how we look at it. We can imagine that, perhaps, there is something we don't know about that Obama knows about that makes this appropriate. I've been reading such wishful thoughts on DailyKos, etc. I agree with Greenwald that such "trust" of leaders is bad for democracy.
