The reality is that Trump's character is fine. And his policies are great.
As for his personality, well, yeah, he brags a lot, and he goes to extremes. But the one thing you can always count on, without fail, Trump puts America and Americans first.
Watching Trump speak, it becomes obvious he is NOT a career politician who all have tons of experience in giving smooth speeches.
Trump should be judged by his actions rather than his bragging and sparring on TV. As you said every ACTION he takes is America First. That was not the case with all previous recent presidents, including Reagan.
