This 4% doesn't translate directly into Obama's 4% margin of victory in 2012, but better poll-crunchers than I are also scratching their heads. A friend remarked that Evangelical contacts who voted for McCain in 2008 stunned him in 2012 with announcements that they were not voting. He says a dozen Christian leaders were touting a new found Christian Ethic of not voting. Not Voting, is a vote for Jesus! to quote just one guy's Facebook page.
Am I blaming white Evangelicals for Obama's 2012 electoral success? No, it was fully a product of Evangelicals, Mainline Protestants, Catholic, Jews, secular-agnostics and aheists, of all ages, both sexes and all races, acting or failing to act more or less as expected.
There really weren't any big switches between 2008 and 2012... except that confounded increase in non-voters.
But we are talking Catholics here. I am not blaming Obama's victory on Catholics alone, just pointing out that over half of them who did vote, voted for the Communist Baby Killer.
That is incomprehensible, not to mention reprehensible. Ditto, the American Cardinals who cannot seem to hitch up their purple drawers and do the right thing.
It makes sense to not blame Christian denominations who vote 80% against democrats, for democrat victories, it does make sense for conservative political activists to point out Christian denominations that do vote democrat, like the catholic denomination for instance, especially on threads that imply that the Catholics are the Christians resisting the left and their agenda.
