Trump supporters do remain blissfully unaware. I've known people like this for years, always happy, had not a clue what was happening in the world, to say nothing of their own country. Could probably not have named the Vice President at the time.
Now you take that same person and make him a Trump supporter, he will be angry about all kinds of stupid shit, but blissfully unaware of anything that might make him feel depressed, or distraught, over what is happening in the world.
They know nothing about the rest of the world and think Trump is best President in history. It's that simple to them.
