You are correct. Trump isn’t convincing anyone, he is just stating a widely recognized (but not admitted to) fact.
Trump is a populist.
He isn’t leading people in new directions. He just states what the silent majority has been thinking (but afraid to verbalize, because...PC police).
The establishment stopped listening to The People and was treating The People like serfs they ruled over. Recipe for some sort of revolution and we see it in both parties. Ballot boxes this time or next time it may be the revolt by bullet boxes.
