The left knows the facts but you have to realise that this war against Trump has nothing to do with actual policy. It's all about launching a campaign to reclaim the turf they have been losing to the republicans since 2011.
None of the demonstrations are spontaneous. They are all funded. None of the so called left wing journalists is writing or saying what they actually think. They are merely pawns in the ideological battle. The left are defending their masters just as the right are.
It's hardly a revelation. This has been going on since the dawn of mankind. The only difference is that with social media and youtube the battle is now being fought out in the open in full view of the world.
