I’m leaning toward asteroid impact or Yellow Stone caldera eruption in 2018. Nothing else seems to faze the uniparty.
The trouble with Yellowstone blowing is it would mainly take out the relatively sane center of the country and spare the libs. Properly sized asteroid in ocean might take out coastal libs without doing much to center. Once touted volcano collapse in Canaries might cleanse east coast. Cascadia generates magnitude 9+ quake roughly every 300 years and is overdue. That could cleanse NW coast.
Ha..wait till the next global cooling cycle kicks in....sometime in Trump's second term
