"In the enclosed chart, these exit-poll figures are compared to the certified vote count in each state, and the difference is shown as a bar. The pattern of the bars clearly shows that the preponderance of the differences favored George Bush. Statisticians who have analyzed the figures all agree that the odds of this pattern occurring by chance are about one in a million."
Actually, I make it about one in 13 billion.

"The other chart enclosed gives the figures for the four states in which the exit polls indicated a different winner than the candidate who was declared the winner by the certified vote count. Ohio had the largest difference (3.4%), which is far beyond the error rate in exit polls conducted by Edison/Mitofsky over many years."
This is a strange analysis*. Where the votes are close, any error in the exit poll will be more like to actually predict a different result from the count. The exit poll could be out by 20% in DC and still predict a Democrat win. I don't see the point of this analysis. But, whatever: of these, four, a discrepancy of 3.4% for Ohio was indeed the largest. But it is not as large as discrepancies in many other states, and it certainly isn't larger than many errors in previous years.
*Edit to add: by the above, I mean that singling out states in which the exit poll had the non-winning candidate in front is just one way of singling out swing states. There are others, but the evidence suggests that the greatest errors were not in swing states but in the bluest states. See my own chart:
