Over the last few days, the absence of Archbishop Charles Chaput from the Democratic Convention roster has gotten a lot of attention, but has a Catholic bishop ever been invited to speak or pray at a Democratic convention? Was Cardinal Egan invited when the gathering was held in New York in 2004? Or Cardinal Mahony, when it was in Los Angeles in 2000?

For that matter…when was the last time a member of the Catholic hierarchy appeared at a convention for either political party?
