Frist is a lovely man, but highly ineffective as Majority Leader.
Too bad I like the guy.
Over time, that may improve. Keep in mind that the Senate Majority Leader, of either party, is elected by his peers, and service to the body, the institution -- okay, the Old Boys' Club -- is the first criterion he is measured by. In this respect, Tom Daschle in retrospect looks to have been a partisan midget, the kind of man reviled in e.g. Advise and Consent, and nowhere near the stature of his predecessors like Mike Mansfield and Howard Baker. OTOH, he wasn't as base as Lyndon Johnson, so I guess that's saying something.
