Don't think they are interested in the Senate. It just doesn't seem that way to me. Guiliani is testing the waters for 2008 already and Pataki has not ruled it out. I don't think they could care less about the Senate race. Just a gut feeling I have. Hillary will run again in 2006 to keep that so that if she loses in 2008 she will still have her Senate seat. She's is cunning!
pataki would make a good senator actually, I think he has run out the string as governor, and with the current legislative senate makeup where his own republican party is over-riding his budget vetoes - what's the point.
