Probably because it hurts the narrative they want to promulgate. Both the Democrats and the Republicans are out to get Roy Moore. The establishment hates him and they are now trying to destroy him.

Do you recall the name of the person who was mentioned as one of these pastors?
Yes. The commenter was “Caston Misty Smith.”
