"This Republican Secret Weapon"

"What fuels the Republicans' political strength, in other words, is not current white Christian population levels, but the fact that white Christians historically turn out to vote at higher rates than nonwhite and non-Christian Americans. These higher turnout rates are driven by a number of factors. Voting is highly correlated with other forms of civic participation, such as church attendance. Voting is also highly correlated to education levels, and white Christians are more likely than nonwhite Christians to hold a four-year-college degree. Finally, voting is a habit that has been strongly emphasized in white Christian churches, especially among white evangelicals since the rise of the Christian right in the 1980s."

Robert P. Jones at The Atlantic writes that since 1980, "[m]ajorities of white Christian groups—including white evangelical Protestants, white mainline Protestants, and white Catholics—have voted for Republican presidential candidates, while majorities of every other group—including nonwhite Protestant and Catholic Christians, non-Christian religious Americans, and the religiously unaffiliated—have voted for Democratic presidential candidates."
