OK, I will admit he spoke the loudest and crudest, but whether he or you say he said it first is a lie.
He made it a real issue first. Saying it first is useless if no one is hearing you. If Cruz doesn’t know how to galvanize the country towards an issue then he’s not the right guy in my opinion. McCain also said you have to secure the border first but his tone made made it a foggy issue. Trump made the contrast sharp and the issue/problem clear. You can at least give him that. Being against someone doesn’t mean everything they’ve ever done or set is garbage
