By what specific mechanism could a Trump presidency cause them to lose access to birth control or abortion?
The trend in the House and Senate and many state governments since 2008 is far more concerning to me than Trump's election.
Did you forget that the Democrats controlled the House and Senate until 2011? In fact, the Democrats had a filibuster-proof majority in the Senate until February of 2010.
Trump also doesn't seem to have much of a view at all, during campaign he expressed one thing and its opposite multiple times, he craves attention and acceptance and if the GOP does that (and lets him enact the petty revenges he's know for) I don't expect he'll have any issue enacting evangelical policies. Hell, he explicitly stated he'd leave the presidential busywork to his VP.
