I can't stand Trump, but unless by "good for the country" you mean "matches Dustin Arend's pre-existing political views", this shouldn't even be that hard.

I'm not holding my breath that anyone will do it, but there is a decently strong case to be made. You didn't ask for the argument to be incontrovertible, or for it to mention all facts. Given the parameters, there are at least two approaches that yield decent arguments.
