mediamatters clearly has a soft spot for Bill O'Reilly.

The politely explain what is implausible about this claim

O'REILLY: John Kerry and Edwards can -- can say that [they condemn negative
campaigning], but they're being a little bit hypocritical if they don't
address the character assassins, which have been hired by the Democratic
Party: George Soros ...

Right. The Democratic party has hired George Soros. To be an honest employer, I should tell Bill Gates, who is mowing my lawn, that he might find a more generous employer if he were willing to assassinate George Bush's character.

I'd like to think that this borderline psychotic claim is a sign that O'Reilly is feeling stressed by the ratings or polls or something, but I know he has always been nuts.
