Believe it or not, this comic doesn’t intend to trash all conservatives. The point of this cartoon: Reagan serves as a good example of what it is to be conservative. Trump contradicts many of these conservative principles. His supporters try to have it both ways. They claim the philosophical foundations of conservatism, while promoting knee-jerk populism that contradicts these foundations.
I don’t consider myself Republican, but even I know that conservatism is actually supposed to mean something. If the “Make America Great Again” camp wants to support their candidate, fine. But they’re not Conservatives. They shouldn’t get away with assuming that label just because they like how it sounds on them.
