To be fair to him, he was probably scared as hell he'd get nailed again. Lol, poor guy. But here's a hint for him: Don't run for president unless you're serious about it.
YES - think about it - any of these folks could spend 1 hour a day - just reading WIKIPEDIA - and know 99% of what they'll need to know entering office.
What regions are controlled by what groups, what conflicts led to that, and how the money, resources, military and people play into it.
He should be able to speak reasonably well on most major nations of the world, regarding these factors. All of them should.
We KNOW hilary can. Trump is scary... "I know more than the generals".... at least Johnson owns what he doesn't know. Trump would have bluffed it better, but bullshitted us as well.
