Christianity... where's the knowledge?

In terms of the current U.S. presidential elections, the only candidate in which I was even mildly interested was Romney, who dropped out of the race shortly after losses on Super Tuesday. One of the most common reasons that I've heard Christians give for not supporting him is that he happens to be a Mormon.

Yet in its analysis of biblical references in speeches by Mike Huckabee, a Southern Baptist and contender for the Republican presidential nomination, NPR notes that:

"Half of Americans can't name any of the four Gospels, and that includes the Christians," Prothero says. "And half don't know that Genesis is the first book of the Bible. Those are much easier questions than things like, you know, 'What's the loaves and the fishes story?'"

Yet, these same people are inclined to reject a political candidate for not "sharing" their beliefs. ("Sharing" being in quotes as, given the vacuity of knowledge of many Christians today, what is there being shared? Mormons (and Muslims), after all, do still at least employ the name of Jesus, albeit not with the same underlying meaning.)
