Trump has no recognizable policies. Just rants about being persecuted, and punching people in the face (especially reporters). And implying he will seek revenge on those who wronged him.

Oh, that's not true. Or rather, Trump may not have formal policies, but he has lots of positions.

Trump is an immigration restrictionist - an extreme hardliner on that issue. He disfavors American interventionism abroad, almost to the point of being an isolationist. He dislikes regulations and the regulatory state, but generally supports the idea of industrial policy to promote favored sectors or constituencies generally. He is against cuts to the most popular entitlement programs (Medicare, Social Security). He supports appointing conservative judges and justices. Etc.

None of these positions are developed enough that you might call them a "policy" - there aren't any white papers or 16-point plans in his nightstand. But it's very clear that MAGA stands for, in terms of the broad strokes of where his Administration would fall on a number of significant issues.
