What I would like to see is a requirement for Senators and Representatives to be in their respective states or districts in order to cast a vote.
The Senator from Vermont must vote on a secure link to Washington from his office in Burligton.
Then hop in the car and go see my congressman face to face, and the citizenry would have a greater impact. The special intrest lobbies would have a far tougher job, having to travel all over the place for face time with several congressman.
