After looking at the partisan breakdown in Utah found by the CNN exit poll in 2004, I decided for the heck of it to look at the breakdown in Massachusetts found in
that exit poll. There were less Democrats than I expected. That isn't the point of this thread, however. The point is in the section on voters' religion.
If you pan down to the part that covers religion, you'll find that Kerry took the Protestant vote by 60%... and that Catholic voters were nearly completely even. In Massachussets. Where the Catholic Democratic nominee was from. In fact, Bush lost 6% of the Protestant support he had in 2000, but gained 17% among Catholic voters.
Is there an explanation for this, or is this likely one of those "1 in 20" sort of statistical failures?
