Mitch McConnell is truly the single person most responsible to why we are here now.
If the historians in the future (-assuming it is one of tyranny-) look back at these times they will see that McConnell was the key.
He is the biggest contributor to the concept of authoritarian rule. Starts with him denying any legitimacy to over 50% of the US population and their support of Obama through his obstruction and overt statements that he would do so. The most direct expression of this was with Merrick Garland and refusal to even have him considered for the Supreme Court. Forget representative government or even our history of democracy.
His enabling Trump for the last two years is just in support of the path to tyranny. McConnell does not believe in Democracy. He is for Authoritarian rule- his actions demonstrate this. Trump is just the tool or the path. McConnell is the method.
