I don't know how it works in the US.
In my country for someone to reach such high position, as to be going to be elected president, he must already have showed loyalty to the system.
If you don't show loyalty to the status quo you have 0 chance to get into the system itself.
Hence, the system cannot be change by the system itself.
That's why I'm suspicious about him.
Anyway I don't know him and of course I might be completely wrong 🙂
