He also doesn't seem to have a real plan to disentangle himself from his business interests as a president. He said he will let his kids run the Trump foundation, but that's still a huge conflict of interest.

The traditional way to avoid conflicts of interests is to put your assets into a blind trust (i.e. liquidate your assets and let an independent person administer them without you knowing about how your money is allocated). I don't see Trump ever doing that.
