America's Least Enforced Law
Religious organizations are tax exempt which means they get a free ride on the rest of us. They get the benefit of government service but pay none of the costs. So government wisely says fine, but you cannot use your tax exempt income for political purposes. Seems like not only a good deal for the religious but also a fair deal.
So Trumpman wants to end it because these organizations are likely to support him despite his amoral behaviour and lack of business ethics.
Now they can go ahead and repeal the law and it will not make any difference in the political world. See first of all churches engage in political activity from the pulpit all the time and second they are never, and we mean never called to account. It is just not politically possible. So like much of what Trump wants to do, it really won't make any improvement in anyone's life, it just further corrupts another part of our society. Go ahead all of you bigoted religious leaders, preach your hate from your pulpit and endorse Trump and the GOP and all the evil they stand for. It's what you have been doing anyway, only maybe in the future it will not be violating the law, not that you really cared about that, did you.
