FIRST, THE EVIDENCE

Now, the claim:

Sixteen years ago, the Democratic Party refused to allow Robert P. Casey Sr., then the governor of Pennsylvania, to speak at its national convention because his anti-abortion views, stemming from his Roman Catholic faith, clashed with the party’s platform and powerful constituencies. Many Catholics, once a reliable Democratic voting bloc, never forgot what they considered a slight.

If you look at the graph, the percentage of Catholics voting FOR Clinton went UP after 1992, so there's little evidence to suggest that the supposed snubbing of Casey had anything to do with later changes in voting patterns. MORE IMPORTANT, the Casey story isn't true, it's part of wingnut mythology, so even if there were voting changes, they wouldn't be caused by an incident that never took place.
