Term limits would not result in a Republican taking Ted Kennedy's seat. Nor would it have resulted in a Republican taking Byrd's seat (although, thanks to Bush, that may be changing. He did appeal to WV voters.)
And I believe that states should have the right to decide how the representatives and senators for that state are chosen.
You sound as though you might have been in favor of William Jefferson Clinton running for and winning a third term. There are v ery good reasons for backing term limits. Once the Kennedys, Specters, Boxers and other left-wingers are entrenched there is no reasonable way to get rid of them. I disagree with you. I think we need term limits.
