All politicians make promises, but to me is keeping more of them than others. And some of the ones he didn't keep are out of his control like the ACA, but he did take away the penalty for not having insurance.
He promised:
More jobs
Stop getting the short end of international deals
Military pay raise (not really is doing, but every few years a raise comes around)
Lower taxes (subjective depending what bracket you're in. My taxes will be lower in 2019)
Promises he didn't keep so far
Wall (working on it)
Signing reciprocity (bill never came to his desk)
ACA replacement "make it better" (see above)
Protect gun rights (bump stock ban)
