<< But on matters like abortion, gay marriage, etc., he has essentially conned the social conservatives.>>
He has.  But they, in turn, have co-opted him. There is no evidence that Trump is even remotely interested in the issues that matter to so-called social conservatives, but he is surrounded by people who do care about them. Mike Pence is an unrepentant, prolific gay basher, and Sessions is a reliable "social conservative" who will pursue policies designed to constrict or reverse the advances in civil, political and human rights of various minorities.
