I heard A LOT of empty rhetoric. The ONLY specifics i heard was his desire to impose a 35% tarrif on imports. Which i believe should be considered. Not necessarily that amount but a tarrif needs to be on the table.
Other than that all i heard was "I am great & will make America great by default"
Politicians frequently talk in generalities. I'm kinda used to it. But I can't remember anyone running for president who ever talked more without really saying anything at all. In fact, Trump often sounds like a complete buffoon compared to the rest of the candidates, and all things considered, that's no easy task.
