Many priests obliged their parishioners not to vote for Clinton because she was for abortion. The truth of the matter is that this so-called clergy wanted to please the wealthy conservative evangelicals who fill the collection basket. To them Trump's lack of morals and bad temperament was okay because he was not a "baby killer".
They will see that Trump will not do anything to stop such killing when he becomes president, and that will be fine with them because all that conservatives want is a president who will "take care of us before he takes care of the lazy poor".
In their homilies, many pastors instead ask parishioners to spiritually and financially support women and encourage them to keep their babies. That is the most that we can do because, however horrible, we have to accept the reality that Roe vs Wade is the law.
As for women who abort out of convenience, no law will stop them. They will do it in back alleys as before. In this case, pastors should lead prayer for conversion of hearts.
