With all the work being done in the Catholic community, I think ppl will know.
Besides, due to the election laws for religious organizations, religious groups/churches/synagogues, etc are not allowed to directly tell ppl who to vote for or they lose their tax exemption. They have to be careful how they do it.
They usually use Voter's Guides which clearly show the positions of each candidate.
On TV Pastor John Hagee gave a really great sermon a few days ago, and at the end, he said, "Don't you DARE vote for a pro-abortion candidate!" He did not name names, but I'm sure his church is handing out Voter's Guides too.
