Trump has a massive Catholic problem. (Washington Post, 8/28/2016)
Back in 2012, GOP nominee Mitt Romney lost the Catholic vote by just 2 points, 50 percent to 48 percent. And the GOP has actually won the Catholic vote as recently as 2004 and in 5 of the last 11 presidential elections.
But Trump trails among Catholics by a huge margin. A new poll from the Public Religion Research Institute released this week shows him down 23 points, 55-32.
