Whoever was behind the bogus exit polls last November. (I'll look it up tomorrow.)
Right, at # 74 I suggested the promoters of the phony exit polls, but I'm not sure that any news organizations really bought into them or promoted them except internally. In other words, it might flavor the coverage without being revealed to the viewers/listeners.
Remember that technically the exit polls are supposed to be embargoed until the polls of the applicable state close. (Drudge broke the embargo, but then debunked the demographics in the samples relatively quickly, IIRC.)
On election day, I first heard of alleged exit polls with Kerry in the lead was on Sean Hannity's radio show. He was cautioning that the exit polls were horribly inaccurate 4 years earlier and should be considered highly suspect.
Later, Dick Morris stated his belief that someone connected to the Kerry campaign or the DNC was able to inject the skewed early exit poll data into the mix. I don't believe that it was ever resolved whether the skewed exit poll samples were simply luck-of-the-draw statistical flukes or purposeful manipulation. Morris wanted Congress to investigate whether this was a failed attempt to discourage GOP turnout.
Many of the left-wing "Bush stole the election" tin-foil hat wearers base their stolen election belief on the flawed early exit polls.
