I'd probably add "duplicitous" to "ignorant". Of course, there's also a tenable argument that absence of an ideological framework is an improvement on the ideological framework of some of the alternative candidates that could plausibly have won the election if he hadn't announced his candidacy. But it says something about a president when the nicest thing you can say about most of their stated intentions is that they're a mountebank without the integrity or ability to actually follow through.
