I generally agree with Paul’s and Joseph’s argument that as soon as they get a comfortable enough electoral majority, the Democrats will likely move toward restructuring the electoral system in a way that will essentially allow them to maintain permanent victory, through methods like court-packing, increasing the size of the House and Senate, and expanding voting rights to constituents that are likely to vote Democratic (prisoners, convicted felons, non-citizens, minors, etc.). That’s doesn’t mean that formal democracy will be abolished in favor of a one-party dictatorship like North Korea. It just means the Democrats will try to maintain a permanent electoral upper hand like Mexico’s Institutional Revolutionary Party had for 70 years in the 20th century.
Just as many liberals and leftists fear that Trump is an incipient fascist in the vein of Mussolini, many conservatives and rightists fear that the rising totalitarian humanist regime will be akin to either Communism, Latin American strongman regimes like those of Fidel Castro or Hugo Chavez, the government of Robert Mugabe that came to power in the former Rhodesia, now Zimbabwe, in 1980, or post-apartheid South Africa, which experienced a massive economic decline, exploding crime rates, and a wave of hate crimes against Boers and Afrikaners.
I tend to think that fully consolidated totalitarian humanist rule in the US will be more like a hybrid of the European Union and Latin America, which essentially what California is today. The future USA will have Latin American-like class divisions, with the general set of policies that are found in the European Union which, to the detriment of conservatives, means more restrictions on free speech under the guise of combating “hate,” more gun control, a more pervasive “equality”-enforcing bureaucracy, a larger welfare state, and the expansion of the public administration state generally, although I disagree that the EU is inherently more statist than the US is at present, and even less so in some ways. The main difference will be that, unlike Europe or Latin America, the US ruling class has a massive military-industry complex under its control, which must constantly seek out new wars in order to justify its existence.
