Yeah, this was the bit that held me up on the data site for a long time. It didn't seem like succeeding could do anything but depress people. But talking to others in this sphere, there are some legitimate things you can do with the data: for example, Dennis Hastert (R-IL) recently had to resign in part because of some earmark data that someone uncovered; he was replaced by a pro-reform Dem particle physicist a month ago. So I think connecting it up to the media and building voter scorecards and stuff out of it could be effective.
