The Left adheres to principles of Bolshevism, which operated on “democratic centralism”: a democratic majority vote ruled, but that which was voted on was determined by a central party (ensuring any outcome would be acceptable to the practically ruling oligarchy) - to wit, tyranny of the majority pre-determined by a dictatorship. Hence the Left’s loud demands for “democracy”, yet propensity to ignore undesired outcomes by selective abuse of the judicial system.
So the Founding Fathers built a government devoted to individual freedom/liberty, allowing for democratic voting locally but filtering it thru representatives and a strictly limiting Constitution. And so the Left is seeking every conceivable way to subvert the existing system, to twist it into democratic centralism - popular votes on pre-chosen faux alternatives.
Precisely.
