The myth that the early 2004 exit polls were biased for Kerry is refuted by the National Exit Poll (NEP) timeline. Kerry had 51% at 4pm (8,349 respondents). His exit poll share remained constant up to the final 13,660 respondents (51.7%). The pollsters had to switch 471 (6.7%) of Kerry’s 7,064 responders to Bush in order to have the Final NEP match the recorded vote. Assuming that Kerry had 51.7% of 125.7 million votes cast, he won by nearly 6 million votes. The True Vote Model indicates that he had 53.6% and won by 10 million.
