If there's a "hate fest" it's because you accuse people of things they
haven't done, like intentionally misleading others when you can't even
identify a misleading statement.
I will have to resort to more drastic measures in an attempt to show you
that the election exit polls were wrong because of the system used, NOT
because of some conspiracy.

I really think that you should not consider searching for evidence and
presenting a URL and quotations to be "drastic measures." It should be
more like "standard operating procedure."
"Since election day there has been discussion about the differences
between the National Exit Poll and the estimates from the Cross Survey
from all state surveys. Some estimates differ by several points among
certain demographic groups, most noticeably among Hispanics. These
differences appear mostly among demographic groups that are both
relatively small (8% or less of the voting population) and those that
tend to be geographically concentrated."
"One way to reduce error is to take additional steps to keep the
interviewers focused on strictly following their interviewing rates in
order to properly sample voters within each polling location. This will
be made an even greater priority in the future. We will develop
additional steps in the recruiting and training process to make certain
that the interviewers are following the detailed instructions that we
give them."
"For the 1,460 exit poll precincts where we have both exit poll tallies
and final vote returns, we calculated an average WPE of -6.5 on the
difference between Kerry and Bush."
"While we cannot measure the completion rate by Democratic and
Republican voters, hypothetical completion rates of 56% among Kerry
voters and 50% among Bush voters overall would account for the entire
Within Precinct Error that we observed in 2004."
Anyway, you can read the rest for yourself. The point here is that I was
right, the exit polling company HAS offered up they made an error, and
got it wrong as I suggested before.
I don't really see it that way. They are saying that large differences in
completion rates by Democrats and Republicans would have to exist to
explain the numbers, but they are not able to directly measure those rates
so we can't really tell what happened. They are also saying that large
prediction errors in some concentrated minority populations could be
accounted for by sampling error that could be reduced by doing a better
job of training their interviewers.
Here's where you have a point: In 2004 they undertook a larger exit poll
than in previous years. This meant hiring and training twice as many
people as before. It seems to have meant hiring lower quality people and
not training them as well. I was told years ago that US census data was
not as good for the big census years as for intermediate years. The
reason, supposedly, was that census workers were very poorly trained for
the big, complete census polls, but better trained for the smaller,
incomplete polls. The smaller samples were of better quality though
smaller, but statistical analysis was able to use the smaller samples to
get better answers. That sort of thing could have affected the exit poll
results in 2004. More data is not necessarily better.
But then we have the other evidence of fraud in Ohio, and we have this
information which seems to strongly contradict the Mitofsky theory -- from
Kennedy's Rolling Stone article:
Now, thanks to careful examination of Mitofsky's own data by Freeman and
a team of eight researchers, we can say conclusively that the theory is
dead wrong. In fact it was Democrats, not Republicans, who were more
disinclined to answer pollsters' questions on Election Day. In Bush
strongholds, Freeman and the other researchers found that fifty-six
percent of voters completed the exit survey -- compared to only
fifty-three percent in Kerry strongholds.(38) ''The data presented to
support the claim not only fails to substantiate it,'' observes Freeman,
''but actually contradicts it.''
What's more, Freeman found, the greatest disparities between exit polls
and the official vote count came in Republican strongholds. In precincts
where Bush received at least eighty percent of the vote, the exit polls
were off by an average of ten percent. By contrast, in precincts where
Kerry dominated by eighty percent or more, the exit polls were accurate
to within three tenths of one percent -- a pattern that suggests
Republican election officials stuffed the ballot box in Bush country.(39)
How could that happen if the inaccuracy is due to oversampling of Kerry
voters? It just doesn't make sense.
