I think it's possible to argue in a sane and rational way for Specter to not be granted the chairmanship, or to ensure that there is a substantial guarantee of his good behavior (perhaps something in the resolution seating him that he remains in the seat "at the pleasure of the Majority Leader," granting Frist sole discretion to throw him out).
It is totally possible, however, look at many of these threads and the language being transmitted to Senators and the White House. It quickly went beyond sane and rationale to shrill, insulting and demanding.
