Frist Twisting Slowly in the Wind

How has Bill Frist fared this year? Over at TPM, Josh Marshall ponders:

A) Who is the last Senate Majority Leader to have as bad a six months as Bill Frist has just had?
B) Has Frist's utter fealty to every direction of the White House now become an embarrassment even to members of his own caucus? Just out of some sense of residual institutional prerogative?
C) What does it say about Bush/Rove's opinion of Frist that they are now happy to humiliate him publicly on something close to a weekly basis?

One rule of politics I've learned is to not let your friends look stupid. But hey, what do I know? Karl Rove is a genius, and I just write a blog.
