Nader will get less than 1% of the popular vote.  Honestly, I would not take any stock in polls pitting McCain against Democrat A.  

Our candidate is undefined, theirs is known.  Given the huge turnout numbers and donations, do you really think Hillary voters will cross over or stay home, or Obama voters will cross over or stay home?

I doubt it.  Democrats win in 2008.  Now its just a matter of whether the Bushies will remove the "O" keys or the "H" keys from the computer keyboards before turning over the keys.
