Pardon my indifference / how radio became a right wing haven

There's a vigorous debate , left-of-center, about the Hunter Biden pardon, and while the likes of Jon Stewart, Leigh McGowan (aka "Politics Girl") and Rep. Jasmine Crockett all have hot (or hilarious) takes, I'm sort of indifferent but certainly not upset. Post-election, I've focused a good bit on the need for the left to have its own media "ecosystem" the way the right was grown theirs the last half century-plus. Oddly enough, NPR's "On The Media" focused on how the radio dial got to be so overtly right-leaning. TL/DR: racism to religion to ending 'Fairness' to deregulation of ownership.
