White evangelical Protestants voted as heavily for Republican candidate Mitt Romney as they did for the GOP candidates in 2008 and 2004, and they made up about the same share of the electorate as they did in the two previous elections.
Barack Obama won 60% of the vote among those younger than 30, down from 66% in 2008, but his youth support may have been an even more important factor in his victory this year.
Obama's margin of victory was much smaller than in 2008 and he lost ground among white evangelical Protestants and white Catholics. But the basic religious contours of the 2012 electorate resemble recent elections.
