There's a difference between voting citizens making their wishes known by phone calls, letters, and financial contributions, and a church leader doing the same thing using his position & title and the money their people donated in the name of charity. And it's a whole different thing when anyone uses their position to force other citizens to vote in a certain way.
There's no doubt in my mind that Jerry Falwell calls legislators ... or has his staff do it, more likely. When clergy use their holy pulpit as a bully pulpit, I have a problem. As I said before, special status comes with special strings. A religious organization that wants to get into politics ought to be ethical enough to give up their tax-exempt status if they're not willing to hold up their end of the bargain.
