We must destroy the Republican party. Fairly, but utterly.
Then in 2020, Trump must be crushed at the ballot box. His corrupt administration must be thoroughly investigated, and any criminal acts punished. More importantly, the economic base of Republican plutocracy — Wall Street, monopolist corporations, and idle rich heirs and heiresses — must also be crushed. Monopolies must be broken up, taxes on the rich and corporations dramatically increased, and the size, profitability, and power of Wall Street sharply reduced with cricket bat regulations.
Meanwhile, Democrats must strengthen their own political base by strengthening democratic freedoms. They should make D.C. and Puerto Rico states, establish an inalienable right to vote, make Election Day a holiday, and strengthen and update labor law to spark a new wave of union organizing. Then they must overhaul the economy to cut the middle and working class in on the fruits of the last 40 years of economic growth, actually provide health care for all, and perhaps strengthen the welfare state for parents and children. Only by establishing a new political economy that functions for the great majority of the citizenry — as FDR and the New Deal Democrats did in the 1930s — can Republicans be firmly exiled from political power. For a political party as diseased as the GOP, a generation in the political wilderness is just what the doctor ordered.
