They ARE NOT all invited:
“But, in 2004, the New York Times reported, neither President George W. Bush nor Sen. John Kerry were invited; and, in 1996, neither President Bill Clinton nor Sen. Bob Dole were invited. Clinton was reportedly not invited because he had vetoed the ban on partial-birth abortion. Kerry was reportedly not invited because he was a pro-abortion Catholic.”
Right. But notice that in those cases, neither candidate was invited, either the abortion lover or his opponent.
What were the sins of Bob Dole or G. W. Bush? The Cardinal and the other hosts didn’t want to make a political statement by disinviting one candidate, so they omitted both.
That would have been the preferable choice this time around, I think, especially since both candidates have serious political misdeeds to account for.
