Did the Majority of the U.S. Bishops Support the Democratic Ticket?

Some time back I cited a column in the Washington Post which claimed that the Bishops supported the Democratic ticket. Because of the criteria that have been employed to support what I think is a large majority of the Bishops, I found that claim to be surprising. Someone who works for the Bishops (who prefers to be anonymous) has written me to say that the claim of Bishops supporting the Democratic ticket is not at all plausible. I would welcome any light that can be shed on the subject (understanding that no one followed the Bishops into the voting booth).
