Yeah, let's just toss out that whole constitutional authority thingy. After all, it's only a piece of paper that was written by a bunch of rich white guys two hundred years ago. What did they know?
I guess your point is the Senators should not use their own intellect in deciding their vote but should just say "whatever"..right? What's your point..that Lott and Hatch acted properly and they should continue to use that logic? Why are they there then if their vote is predetermined by the President? We could just elect signs and glue them into the seats in the Senate chamber.
