I predict that Trump himself will survive the Mueller investigation and will win-re-election in 2020 when the Greens or some other progressive coalition run a third-party candidate who siphons off just enough votes in a few key states to give Trump an extremely narrow EC victory over a weak and divided Democratic Party and ticket.
However, Trump will suffer a major health event soon after his second inaugural and will be replaced by Pence. RBG and Kennedy will be replaced by far-right extremists nominated by Pence, and the new Court will rule that Social Security, Medicare, collective bargaining, public schools, and all government regulation of any sort are unconstitutional restraints of trade.
The 2020s and 2030s will witness a gigantic outflow of the educated and skilled to Canada, Europe, Asia, and parts of South America.
By 2040 our economy and social structure will be essentially feudal, with virtually all wealth in the hands of a tiny number of corporations, churches, and unimaginably wealthy individuals who live in isolated compounds far from the impoverished, drug- and religion-addled masses. The federal government will be little more than a huge military and a compliant Republican-run Congress in Washington D.C. with all day-to-day administrative decisions made by state governments entirely owned by the feudal corporate lords who run things.
Education will be non-existent save for the children of the elite, and our economy will be dwarfed by the educated and increasingly-skilled workforces of China, India, and Europe. We will be dependent on technology we buy or steal from the industrial and technocratic countries elsewhere in the world, as the Republicans of the 2020s and 2030s finally realized their dreams of killing off higher education in favor of a national network of Christianist Bible Universities.
The Great Plague of 2053 will effectively finish off the country as a functioning modern state, as a completely drug-resistant flesh-eating disease kills or severely weakens 70% of the population, which was left defenseless because of the other great achievement of the Republican Party, which was the closing of the CDC, NIH, and every public health office in the country as “insults to God in his wisdom.”
In 2055, Russia will seize the moment and will invade and occupy Alaska, taking control of its oil and mineral resources, and the 103-year old Vladimir Putin will made a triumphant visit to the land formerly owned by Sarah Palin where he will plant the Russian flag and Orthodox cross to signify Russia’s retaking of its former territory. In 2060, Republican President Donald Trump Jr. will abrogate the Constitution and formally turn over ownership and administration of the United States to Russia. In return, Putin will crown Donald Trump Jr. Czar Donald I of the American Territories.
