Yes, the majority of Catholics voted for Obama, but not actively practicing Catholics. Catholics who work at their faith did not vote for Obama.
In addition, the majority of single women, Hispanics, Asians, union members, and young people voted for Obama. I believe the majority of farmers voted for him too.
This election, most people voted along their special interest groups and sold out the greater good, the unborn, and the war on terror.
We don't know that. We only know that a majority of those polled who claimed to be Catholic admitted voting for Obama. I would venture a guess that a quite sizable percentage of Catholics who were eligible to vote, along with a sizable plurality of the electorate, didn't vote at all, as is the usual case.
