I am not at all intending to defend US evangelicals who from a european point of view are religious extremists. We are lucky to have only a few of those here. But those US evangelicals would say that Trump was their tool to overcome liberal abortion laws and that is very well within their values. I would say they even limited their view on Trump to exactly this: he will deliver conservative judges all over the place including the Supreme Court who will then dismiss liberal abortion laws and allow restricting ones. And he did. Well, actually McConnell did ("This president will sign everything we give to him") but Trump is getting al the credit.
