Here is a document from the Trump campaign about his short term goals, I hadn't read it yet when I posted above but I think most of my points survive: https://assets.donaldjtrump.com/_landings/contract/O-TRU-102...

No mention of ending abortion. I agree that it would be sexist and catastrophic if it happens, especially given the state of american health insurance coverage.

EDIT: from this document it looks like he plans to target undocumented immigrants who have a criminal record -- the process will probably be very disruptive, I think this is the single policy of Trump that could cause the most human misery, but it seems possible that the process could give the others a more secure status.
