As for now (I mean, half a year ahead) I feel like Bitcoin is the least of Trump's concernes. Which doesn't mean he'll leave this issue alone if he comes back for a second term
I don't even think it is not his issue just because he is looking at an election, he has also been focused in other businesses even globally like having interest in Japan and China. I just think bitcoin isn't no body's business and it will be difficult to be discouraged because it is decentralized. China has tried in 2017 but no major success on that and they are coming back.
