The chart was made from results of a new Public Religion Research Institute Survey. The survey was done between August 10th and 16th of a random national sample of 2,014 adults, and has a margin of error of 2.6 points.
It shows Hillary Clinton with a substantial 13 point lead over Donald Trump. Trump does have a 39 point lead over Clinton among white evangelicals and a 10 point lead among white mainline protestants. But Clinton overcomes that with an 87 point lead among Black protestants, a 23 point lead among catholics, and a 31 point lead among the unaffiliated (the largest group).
