Frist is a good man , conservative and sincere but probably too wimpy and nice for the role of senate leader or even taking on the Democrats. He is better suited for a local role, say the governor office.
Perhaps now all the people who wanted a pleasant but dull guy as the GOP nominee will shift their support to Gov. Pataki. He's another one who shouldn't bother, IMO. If lightning struck and he were to get nominated I can't believe he would even carry NY.
