There's a difference in doing politics in a generic sense of good vs. evil and freedom vs. totalitarianism. That's fine because it's universal and has wide appeal.
But if there are going to be Trump and Republican stand-ins that are obvious and one-dimensional whose sole purpose is to act as strawmen in order to prop up the author's personal politics, then that's something that I could live without.
Political diatribes of this type in comics are always poorly done -- especially in superhero comics. Can't think of a single time it wasn't.
