In his re-election victory, Democrat Barack Obama narrowly defeated Republican Mitt Romney in the national popular vote (50% to 48%)1. 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.
Vote Choice by Religion and Race
Religiously unaffiliated voters and Jewish voters were firmly in Obama’s corner in 2012 (70% and 69%, respectively). Compared with 2008, support for Obama ticked downward among both Jews and religiously unaffiliated voters in the exit polls, though these declines appear not to be statistically significant. Both of these groups have long been strongly supportive of Democratic candidates in presidential elections. Black Protestants also voted overwhelmingly for Obama (95%).
At the other end of the political spectrum, nearly eight-in-ten white evangelical Protestants voted for Romney (79%), compared with 20% who backed Obama. Romney received as much support from evangelical voters as George W. Bush did in 2004 (79%) and more support from evangelicals than McCain did in 2008 (73%). Mormon voters were also firmly in Romney’s corner; nearly eight-in-ten Mormons (78%) voted for Romney, while 21% voted for Obama. Romney received about the same amount of support from Mormons that Bush received in 2004. (Exit poll data on Mormons was unavailable for 2000 and 2008.)
Jews accounted for 2% of the 2012 electorate, and Muslims and members of other non-Christian faiths together accounted for 7% of the electorate. The religiously unaffiliated made up 12% of 2012 voters; the religiously unaffiliated share of the electorate is unchanged from 2008, even though the religiously unaffiliated share of the adult population has grown significantly over this period.
