I'm coming to dislike most of the "old guard". A Westerner like John Kyl or John Ensign would be a nice change - the battleground for the GOP's future is going to be the West, since the South has been thoroughly conquered. But I'm not sure there is anyone in the Senate - with the possible exception of Tom Coburn - whose primary motivation isn't reading his own press clippings every morning. ;)
Coburn would work for me too. Seems to be on the ball. But would he have the clout with others?
