You are deluding yourself if you think he is not serious about this. What he is doing now in the coal states is saying he supports coal. He is lying his tail off because in reality his plan is to eliminate coal(and other forms of energy!). He wants to bankrupt America and then rebuild her as a communist society, it is always the way with marxists. That is how they operate and he is deadly serious about bankrupting coal companies.
We’ll see. I think it is either a ruse, or he is the most foolish politician ever to live. I don’t think he could get away with it. 300 million unemployed Americans groveling in the street are not likely to be persuaded by his ideological arguments.
