Flames out spectacularly.
By 1992 Democratic Presidential primary voters were firmly Pro-Choice, and Gov. Casey would not have reached the minimum threshold to receive delegates.
The controversy about him not being allowed to speak at the convention was just a media invention trying to create a story when there was really none there.
DNC Chairman Ron Brown had a rule that in order to speak at the convention, you had to endorse the presumptive nominee Bill Clinton, only Kathleen Brown, California State Treasurer was allowed to speak without endorsing Clinton because she was the heavily favored frontrunner for the '94 California Gubernatorial nomination.
Gov. Casey could have circulated nomination papers in order to get his name placed in nomination and then spoke for himself during the seconding speech.
