Why does this continue?Why can't the new members take their seats by 2 weeks after the election? We have air travel, hotels aplenty, and other means of getting them in place without delay.
Failing that, how about letting them participate in votes via an Internet hook-up? Virtual Congress, 1.0. That would give the outgoing Congressmen time to pack up, say their good-byes, sell their houses, move their belongings, and get the kids enrolled in the new schools.
Having a lame-duck Congress is one of those artifacts of US government that needs to be re-thought.
