More importantly, how did we get an almost 50/50 split? Which in my circles is not true by any stretch of the imagination.
This has baffled me for years and I think with the 2020 election we see the answer.
One side cheats like a motherfucker and uses lots of pomp and braggadocios bullshit to inflate their apparent numbers. Then lies about it until… shit, I have no idea when they'll stop.
