This is a re-post of something I wrote for the Lowy Institute earlier this month. The original is here.

So yes, Donald Trump is awful. He is a threat to American democracy, an vain narcissist, doesn’t know anything about nuclear weapons or national security, and so on. I know what you’re thinking, so I will say that I mailed-in my absentee ballot today, and I voted for Hillary Clinton.

That does not necessarily impugn all of his ideas however.
