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 10 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.

A Washington Post-ABC News poll released earlier this month painted an even worse picture for Trump’s Catholic support. He was down by 27 points, 61-34.

If you compare the difference between Romney’s margin among Catholics in 2012 and Trump’s margin among Catholics this year, the 25-point difference is tied for the biggest shift of any demographic group in the Post-ABC poll.
