"Coburn will be like a conservative version of John McCain - a maverick who bucks the party leadersip, only he'll be doing so from the right."
I think your assesment is right on the target. He won't let his fellow Republicans stop acting like Republicans when they get in the Senate. He has pledged to make getting President Bush's judical appointments voted on and approved. He will do so no matter who it ticks off, and the party (and country) will be better for it.
and he is for making those presidential tax cuts permanent!
