Mr. Miller is explicit in his criticism of Tom Daschle, which is interesting and highly unusual.
Zell Miller is nowhere near as naive a senator as he puts himself up to be. The Majority Leader is much too powerful for any reasonable senator to go off insulting him at will.
Of course, Daschle and company are making a true botch of things -- their spin isn't working, and they're showing themselves to be rancid little politics-first obstructionists.
I'm betting that Miller senses this, and is positioning himself for a post-Daschle leadership position.
