Technically, Kerry already merits de facto excommuncation for facilitating abortion and for sacrilege.While we're doing Kerry's rap sheet, did he ever get an annulment for his first marriage?
Based on what chatter I have picked up, that has not been confirmed on paper. Neither has there been confirmation whether Kerry and his current "wife" were married in accord with Catholic sacramental rites.
The Kerry rap sheet would seem to include violations in the following areas:
abortion
sacrilege
scandal
questionable anti-Catholic Secret Society memberships
marital irregularities
and abomination (harvesting embryonic stem cells)
FWIW, the Catholic League says that Kerry eventually said that he did get the annulment. I don't know if he produced documentation or not, but unless he's lying through his teeth, his first marriage was apparently found null.
