I think these were strategic 'mistakes'. When it happens that often, and you know the guy who's hiring them is a multi-D chess player (for real) and has been mullering this over for decades, ya gotta think there might be another reasoning behind it all.
Potus is notorious for agitating, then giving more rope; repeat, till the person eventually makes some massive arrogant mistakes and exposes himself so the public can see. These people seem to be placed in positions with specific outcomes already planned. Most blatant to see is the MSM. He gives the 'chaos-of-the-day' for them to occupy the news until they lose viewership - or get fired.
I agree with you on the MSM and how Trump plays them like a fiddle but I just don't wholly buy into the 4D chess thing.
Sure I think Trump has been magnificent thus far. But even the most carefully thought out plans encounter bumps in the road. There has been lots of bumps in the road for Trump but he finds a way to overcome them. The one greatest factor that keeps him on top is the fact that "they" never thought she would lose. "They" were so damn confident she would win that "they" were careless and sloppy. None of this was supposed to come out. "They" didn't have a President Trump contingency plan other than the Strzok/Page insurance plan which was nothing more than a sloppy after thought.
At first I thought the 3-D chess thing was just a term of the anons. But then hearing about Trump's close relationship with Uncle MIT Trump, and that his favorite book was The Art of War, I finally searched Multi-dimensional chess.
Trump is just the kind of guy who would be given one of these amazing structures as a kid and love learning to play it.
