The hysterical opposition is pure frustration that he managed to thwart what the left thought was the final stage in the Revolution where they would be permanently in power and all obstacles would be swept away, obstacles like uncontrolled elections and Constitutional provisions. They thought they were right at the edge of a Communist system wherein the elite has its dachas and control 0f all material and social assets and the rest of the population is an undifferentiated mass of work units to be increased and moved about and decreased at will. They would be able to finally neutralize and sweep away any hint of opposition to their .5% Utopia.
America will be a hard nut for them to crack. We have been schooled on and have lived with liberty and freedom, we are not going to give that up to the elites without a fight. I guess they did not think we would fight back. Unfortunately they will win eventually, I hope it is not too awful for my grandchildren.
