IDK if you knew Trump before he got into politics, but he's always been really good at walking the edge of liability hyping stuff up, moving from one controversy to the next before anything can stick.
Our system has always kinda allowed for this, but he's exploited it to the max.
You'd be surprised. Changing things for the better in our current political climate has proven to be extremely difficult, even when a large majority is in favor of such change (e.g. - abortion access).
