Rick Santorum won the lion's share of voters in Tuesday's presidential primaries in Alabama and Mississippi who said it was very important to them that the Republican candidate share their religious beliefs.
Except the leading candidates don't, at least not in traditional terms.
Santorum, like Newt Gingrich, is a Catholic; the vast majority of Republican voters in both of the two Deep South states are evangelical Protestants. Once, not that many years ago, such differences mattered greatly. Now voters seem focused much more on beliefs as they affect public policy than on matters of creed.
