Because it's Wednesday and, what, over a year away from mattering.
The short version: Hillary Clinton is still kicking Obama's and John Edwards' asses. Rudy Giuliani is still looking good, though Fred Thompson (at least until he actually opens his frownsome mouth and starts campaigning) should be cause for concern. And Hillary vs. Rudy is looking pretty tight. Some details here, from RealClearPolitics:
