[1] Despite his many, many, many flaws, Biden winning the presidency was a blessing in disguise for the socialist movement. Bernie was free to use his position as Senate Finance Chairman to force through or sit on any legislation with near-anonymity, bending the often listless Biden administration to many positions from his own posthumous campaign. Minimum wage was raised, labor powers were expanded, billionaires were even taxed more - but only after the President got a second term.
[2] '28 was an exciting year for radlibs, since both tickets were all-female, purely by coincidence, allowing compassionate conservatism to win out over Biden-era stagflation with little hubub. In a first, a Republican administration put forward pragmatic and bipartisan policies, taking great lengths to combat homelessness and climate-change. Stewart is often credited by Daily Show Democrats with putting the GOP "on the right track", despite a small relapse following her jarring loss in the early thirties. Hawley won that with his Apple-Pie Populism, but was siphoned by Harrington's third party candidacy.
[3] The younger Lumumbada started off as a southern Obama-lite but became more and more radical as the thirties dawned. In the first hour of his presidency, executive orders for a 10% value-added tax on business transactions, a 0.1% tax on financial transactions, a 2% tax on every dollar of net worth above $50 million, and $40/ton carbon tax were signed with a blue ballpoint pen and put into effect the next day. Minority leader Bassaro, trying his best to emulate the late McConnell, lead walkouts in order to further stonewall vacant SCOTUS seats, only for the Prez to use the Constitutional Appointments Clause to confirm judges Kruger, Gupta, Koh, Jackson and Twitty. Any petty terminations Amazon committed to try and call Lumumbada's bluff resulted in stronger, more aggressive Unions. By the end of his second term, monopolies that gripped the global industry were on the verge of collapse.
[4] The American Overton window had now been firmly shoved to a further left. President X, as they called him, made combating climate change his #1 priority in his first 100 days - a fitting caveat, considering how his home state of Florida had become the new, trashier Venice. Oil rig workers were recalled to the mainland in their millions and given new jobs as windmill farm maintenance. Disenfranchised assembly workers suddenly found the jobs at the plant had returned, tho now they'd be putting together EVs instead. New York City quickly found its skyline dotted with towering vertical farms that employed hundreds of Liberal Arts students. Fun fact: only 21,250 square miles of solar panels are needed to power the entire continental United States, and that's exactly how many American businesses made with government grants, payed for by corporations and multinationals being grabbed by the neck and forced into paying absent tax revenue.
[5] The current president, an Enby Oklahoman who usually wears a hijab the same shade of blue as their John Lennon glasses, sits at the head of a rather calm collection of 52 States. Commonsense legislative reform has allowed for the passage of the NPVIC, allowing the Electoral College to be shuttered and congress to erupt into a calliope of new parties. Soldiers haven't been sent overseas in decades, and police exist only as municipal Civilian Defence Forces. The massive network of solar panels, wind turbines, hydroelectric ocean engines and algae blooms has left America energy independent and net carbon neutral. Employees even own small shares in the industries they work for. The real issue for them to face is a social one, as old-world racism and sexism still exist in small pockets. But they all have time for it now, especially since their social war is against class struggle as a whole.
