(As an aside, maybe if the Republicans would run an actual conservative Republican for President, instead of a "maverick" who misses no opportunity to cut the ground out from under conservatives, they'd get more votes. Hmmm ...)
As far as the people who self-identify as "Catholic" but have no actual present-day connection with the faith, I'm not sure there's much we can do about them. If their (claimed) faith doesn't inform where they spend their Sunday mornings, how much can we expect it to inform their behavior in the voting booth?
This is such a tired old lame argument. I can play that game and get the Evangelical Christian %'s up into the high 80% area. Your church embraced implementation of it's "social justice" beliefs by means of an ever increasing authoritarian fed govt. When a majority of your members actually vote for conservatives it is not by a huge %. If the RCC and it's members really want to embrace supporting conservative values, which include free exercise of religion, I say welcome!
However, I am in that Reagan school of thought that teaches, "trust but verify". IOW, I'll believe it when I see what happens in 8 months.
