The Hill reports this morning that in 1992 "Pennsylvania Gov. Bob Casey (D) was barred from speaking at the DNC because of his anti-abortion rights stance."
This is a common claim, but it's completely false.
There were no fewer than eight speakers at the 1992 convention who opposed abortion rights. Therefore, it cannot be the case that Casey was barred because of his stance on abortion.
That really shouldn't be difficult to understand, but those interested in additional details can find them here.
Here's the short version:
1) Casey wasn't "denied" a speaking spot; that suggests he was entitled to one. He wasn't; nobody is (save, I suppose, the nominees for president and vice president and the convention officers.)
2) There is scant evidence from contemporaneous reporting that anyone other than Bob Casey thought it would be a good idea for Bob Casey to speak at the convention.
3) Casey had not only refused to endorse Bill Clinton, he had actively suggested that the party should choose a different nominee at the convention.
4) It logically cannot be the case that Casey was denied a speaking slot because of his views on abortion, given that severals speakers shared his views.
5) Casey planned to use his convention speech -- the possiblity of which apparently existed only in his own fantasies -- for a single purpose: attacking the Democratic Party.
That's why Casey didn't speak at the 1992 convention: because nobody wanted him to, because he refused to endorse the party's nominee, and because he planned to devote his entire speech to attacking the Democratic party; the speech didn't include the words "Clinton" or "Gore" a single time.
Finally, those who insist on pointing to Casey's lack of a speaking role at the 1992 Democratic convention as evidence of the party's lack of inclusiveness are invited to produce an example of a Republican convention speaker who refused to endorse the nominee and spent his entire speach attacking the GOP's position on abortion without saying a single word in praise or support of the party's nominee.
They can't do it, because there is no such example.
