There was no distinctive Catholic problem for Obama in Ohio. In fact,
white Catholics were slightly more likely to vote for him than white
Protestants. But both preferred Clinton by wide margins—the Protestants by
67-30 and the Catholics by 65-34. White Nones preferred Clinton 53 percent
to 42 percent. Basically, it was with white Democrats that Obama had a
problem in Ohio.
Huckabee got the evangelicals (44 percent of GOP voters) by a narrow
margin, 48 percent to 45 percent. He got the more-than-weekly attenders (18
percent of GOP voters) by a larger margin, 54 percent to 46 percent. The
core, committed evangelicals were on his side. Otherwise, it was all McCain.
