I think it's remotely conceivable the Trump could drain the swamp and return the government to the American people. But there is still the problem of how to extend that condition beyond his term in office. Serious jail time for law breakers after trials in accordance with existing law under the constitution seems to me to be the best hope for a long lasting deterrence against future crimes. Ie. make it clear that America operates under the rule of law and that the law is applied equally to everyone.
