It's supposed to be Frist's job to keep them in line. DO YOUR JOB, FRIST!!
Oh please -- "keep them in line"? He's not a hall monitor and they aren't third-graders (they just play them on TV). They are US Senators -- each one thinks he or she is God's Gift to Government. Voinovich, for one, doesn't need Frist -- he has a very safe seat here in Ohio (sad to say).
