Your position, as you have already stated, is that Trump's base are a bunch of stupid people.
This is not the truth. While Trump's base isn't always the most educated of the population, they do live as ordinary people who wish to do things in an ordinary way. That ordinary way is to investigate and to use the process of the courts. Ordinary, intelligent people realize that their understanding of an issue is limited and that there are limits to their capacity of attention. They realize that the time they spend scanning the headlines is insufficient to then rush off with a noose in hand.
Smart does not necessarily require genius or creative rationalization of errors. "It's not a bug… It's the feature you're too backward and uncultured to recognize." Say the Laputians.
In the world of the blind the one-eyed man isn't king - he is the odd man out.
Anyway - Trump's base is a very smart and aware bunch that does not believe in unmeasured punishment. True, before I was fully aware of just how corrupt our own intelligence agencies were, I was rather suspicious, even against Assange/Wikileaks. Now, I see it as more a sign of the times that our own internal oversight was being used to kill whistleblowers and informants rather than to protect our sources/methods and integrity/accountability to the public.
Don't get me wrong - Wikileaks is not the ideal solution to that problem and presents a large number of its own. Who decides what is and is and is not sensitive information and what does and does not get released? Wikileaks had its own proverbial cannon to point where it wanted, and had its own capacity/motive to deal damage preferentially. Even if not a problem, currently, Assange and company certainly had to pick sides and play their cards in an attempt to use leverage… And that's espionage, just as a reality.
