According to exit polls, Barack Obama was re-elected last night with the majority of the Catholic vote. From Politico:
Although he again lost Protestant voters to his GOP opponent, Obama held onto his advantages among Catholic and Jewish voters. He won 70 percent of the Jewish vote, down from 78 percent in 2008, and he won Catholic voters 50 percent to 47 percent. Romney carried Protestant voters by a 13-point margin, 56 percent to 43 percent.
That’s down very slightly from the 54 percent of Catholics who voted for Obama in 2008. I haven’t seen any polls parsing the numbers on how Mass-attending Catholics specifically voted (in 2008, the majority of Catholics who attend Mass weekly went for McCain). More as the numbers become available!
