I found the dilemma of Mr. Kempton the hard choice of many, including myself. I do understand that. But what mystifies me is when someone says they are pro-life (I have many doubts about that with Mr. Trump) that somehow that means they can do something about it in the white house. No Republican since Roe v. Wade was successful in this regard. Also, I wonder why we think that reducing the number of abortion clinics equals reducing abortion. That was not true before Roe v. Wade, as it is today. 
In my view the bottom line is not merely to make abortion less available, but to find ways to help pull woman out of poverty who tend more to higher incidences of abortion. Mitigating unwanted pregnancies should be the main focus. What candidate has the best chances of helping to do that? It would seem to me that this is a common ground that pro-life and pro-choice supporters could gather around.
