The fact is Romney is winning close to half of the Catholic vote while Newt and Santorum are both Catholics.
The difference is, Gingrich has based his campaign on oil prices, international policy, calling the MSM out for what they are, taking on Obama and his radical agenda, all those unimportant issues facing America. Mr. Oral Moral has focused on the evangelical voters and telling America how to conduct their private lives.
This is based on one exit poll. I don't know how accurate it is or what the margin of error is.
But even if it were true, so what.
Most Catholics don't vote based solely on religion. The vote for who they think is the best candidate.
