It occurs to me that what is happening on the biological level re the Communist virus is being replicated in the political realm re communist ideology.
Communist ideology has invaded blue cities like a virus invaded cells. The ideology has taken over the power centre as a virus takes over the cell’s mitochondria. Information with, and regulation of, the cities are converted to producing new communist agents and propaganda, as a virus uses the cell’s resources to replicate itself and its own RNA. The city will eventually collapse and the replicated communists and propaganda exit to invade and infect other communities in the nation, as the replicated viruses escape the collapsed cell and invade and begin to take over other cells in the body.
The Democrats need to win the Electoral college. They cannot do that if their supporters remain in their traditional locations, and they are struggling to win converts from among conservatives. What to do? Make the fortresses of socialism unlivable, but blame the collapse on Trump, so that socialist-minded citizens flee to better run red communities where they will vote against Trump , who they have been programmed to believe destroyed their life in the blue cities, and in this way swing the Electoral college balance toward blue.
