You could claim that this, like the tax release and Trump's overall buffoonery, are diversionary tactics to dilute opposition to policies like tax cuts for the rich, healthcare, environmental cuts but he does not seem that devious. Or he is that smart and excellent at playing an arrogant and naive liar.

But it does seem like there's a coordinated effort of focus upon certain topics. While other, more troubling ones, go unmentioned or ignored.
If this comes down to a Trump Vs Putin sort of battle. Than my money is on Putin as he's way ahead in both brains and corruption.
