Right wing president elected
On inauguration day, just hour after inauguration, one or more “accidents” kills new president, vice president, speaker of the house, and other Republicans in line for presidency.
At the same time, the Republican majority senate suffers some blows: Republican senators from states with Democrat governors also suffer surprising accidents and death.
Bottom line: Democrats take control of White House, Senate, and Congress; a complete turn around.
Figure out: what states with Dem governors have Rep senators. Figure out line of succession so that Dems take control immediately.
Of course, Repubs will fight this. Therein lies the tension. And there are other, more sinister uglinesses taking place behind both Dem and Repub groups. Maybe a progressive liberatarian type ultimately takes control .
