There is just absoluely to much speculation going on by people who know nothing. At this site there is a thread from a "insider" "knowledgeable source"... guaranteed to be accurate that tells us Spector basically told the President it had to be Miers or Gonzales or the nomination wouldn't make it out of committee. And there is a thread telling us that Spector wants to investigate the WH because they allegedly made a back room deal with some ultra conservatives to get support for Miers.
I've seen a lot of politics in my time... but none as bad as this deal is going.
