Your skepticism is well-founded: there's no reason to believe that Trump has a position on abortion or that he cares about it even a little bit.  More important, we know that the rate and number of abortions will increase on his watch as he and the Republican Congress enact social and economic policies that strip health insurance from millions of people who now have it, many of them as a direct result of the Affordable Care Act. Voting for Trump on "pro-life" (read: anti-abortion) grounds was an act rooted either in ignorance or hypocrisy. A well-informed voter who cared about life issues could not have voted for Donald Trump.
