That's not true since it doesn't matter when Trump messes up, he's a civilian but Hillary and her massive scandals have been while she's been in office. Plus Trump and his core supporters a). don't give a fuck and b). are supporting him in spite of Hillary and the entire system; their support of Trump is a giant Fuck You to the system.
There is a bit of a misconception that Trump only has closet racists and uneducated supporting him, as shown by the polls today it's a lot more than just that. The Republican party always attracts those people anyways but the uneducated vote for both parties. It's spiraled into something much deeper.
Part of what this election is telling us is people are sick and tired of politicians, they are fed up with the bullshit same old lies and false promises, that's one of the main reasons a guy like Trump has support. The fact that a self proclaimed Socialist in Bernie Sanders did so well is further proof of that. People are desperate for something different, for change and not someone who represents every thst came before like Hillary. They give us these options to choose from and this is the result.
