The Herd the Media refers to as the Left got very big after 1970, and definitely have gone mad. They are pretty much beyond help, not curable. I assume a small percentage have been slowly coming to their senses after Trump got on TV in 2015.
Charles MacKay is remembered mainly for his book “Extraordinary Popular Delusions and the Madness of Crowds.” Note the masses that hate a president that has the balls to tell it like it is, and trying stop the 50 year obvious decline of the country and living standards.
Trump was right when he said to the third generation of Americans. “What do you have to lose”? Right, we already lost. Naturally the younger generations don’t know how better things were. Teenagers had money, and businesses did well selling cars to them with 3 year loans.
