In his re-election victory, Democrat Barack Obama narrowly defeated Republican Mitt Romney in the national popular vote (50% to 48%). Obama’s margin of victory was much smaller than in 2008 when he defeated John McCain by a 53% to 46% margin, and he lost ground among white evangelical Protestants and white Catholics.
But the basic religious contours of the 2012 electorate resemble recent elections – traditionally Republican groups such as white evangelicals and weekly churchgoers strongly backed Romney, while traditionally Democratic groups such as black Protestants, Hispanic Catholics, Jews and the religiously unaffiliated backed Obama by large margins.
