What I like best about the whole thing is that it is a slap in the face of the Republican senators who had apparently been telling Jeffords "you don't belong in the Republican party." He took them at their words, and now they have to eat them.
Now we'll see if the "bipartisanism" that Dubya has been gassing about it more than just gas -- can he really work with a democrat-controlled Senate? He has got a lot through so far by arm-twisting and strong-arm tactics (which of course is what finally drove Jeffords from the GOP). Now he will have instead to use tact. Is he up to it? Stay tuned!
