Regarding Feingold's censure motion, Kevin Drum simply states it's serving as a distraction:

Is this really helping convince the public that Bush deliberately and repeatedly violated the law when he approved the NSA program? I'm not seeing it. Political theater is only useful if it actually shines the spotlight into the dark corner where we want it shined, and Feingold's censure motion doesn't really seem to have done that. Instead of pinning our hopes on yet another bright and shiny silver bullet, maybe there's a place for all those boring hearings and investigations after all.
