Your table only shows the percentages among people who voted. It does not say what fraction of each group actually turned out to vote. The original article makes it clear that Romney did well among evangelicals who actually did vote.
Really? With a question like this "Could it have been that many evangelicals couldn’t bring themselves to vote for a Mormon, and simply stayed home?" it looked like another "Blame Christians First" article.
Is your post # 1 part of the article? Naturally I didn't click the link. And since you posted such a short incomplete excerpt, I figured there wasn't anything to read anyway.
