Jerome has word from a pollster that CBS spiked a Florida poll because it showed Kerry up by a whopping 4 points. I had heard that the 4 point poll was what they got after redoing a previous poll they weren't happy with - one which showed Kerry up by 8 or 9.
Now, I have no idea if this poll is a more accurate representation of reality than any other, but there's no chance they would spike such a poll if it showed Bush ahead by that much.
They're just scared of Drudge screaming "liberal bias" at them. Cowards.
