Religious institutions should lose their tax exempt status if they are actively being political or otherwise endorsing candidates, for one thing, or saying "you, dear congregation, should vote this way or that way."
Does that include Churches which bus congregants to the polls for mass early voting?
I very much frown on that, especially if it's an organized church activity. Local and state governments should ideally take care of that, but the thing is, in a lot of communities the church is the social center. So it's very gray.
