I don't think Arlen should serve at all. His health is too feeble to do the job. I'm tired of these guys, older than dirt, hanging on to power and office. They don't have the energy to read the bills, much less vigorously fight for or against anything in them. Byrd's another one. He needs a walker, a wheelchair, and two helpers to take a single step. When in public life, be it a celebrity or politician, retirement can be your friend.
