Your personal anecdote aside I can’t find any reason to think that Catholics vote at a higher rate, unless the democrats just do a better job in voter turnout.
I don’t know any Evangelicals who don’t vote, but I think we need better data than that but I can’t find it so far.
“I don’t know any Evangelicals who don’t vote,”
Agree. No actual data, but I’ve been immersed in Evangelical people (family, friends, fellow students) since I was born. Everyone I know votes — conservative.
