3. We used to have the talking filibuster, why was it made silent?
I'll tell you why, because a more aroused and involved electorate (crazy or not) made it more dangerous to stall public business in public. Anonymity is good for them, but not for us, we need to be watched.
The filibuster used to be used rarely, to be used on matters of principle, now it is used as a fund-raising tool.
Right now deals are being made, policy traded back and forth, and all in "quiet rooms", like Mr Romney says.
