Between the Civil War/Reconstruction, the Federal Reserve, the 17th Amendment, the Military-Industrial Complex, et cetera ad nauseam, the Republic fell a long time ago (and not all at once or at any one particular moment). It's been nothing but shambling and increasingly desiccated revenant for quite a while now.
I am disappointed that I won't get to see the operatives of the U.S. Department of Propaganda (i.e., the corporate media, et al.) gnaw their own tongues off in head-exploding fits of apoplexy, but that would have been a short-term satisfaction in any case. A Biden presidency that many millions will regard as illegitimate will serve the longer-term purpose of further exposing the fact that a continent-wide mass democracy of over a third of a billion people is (and can be) nothing but a ludicrously untenable sham. A Trump victory would have undercut that salubrious result. Now that both "sides" have had a taste of having their noses rubbed in it, our ideological self-segregation can proceed apace. I hope that it will.
