While I'm totally behind a world where Frank Zappa lives longer, the political problems of the US federal government are systemic. The Democratic party moved left out of necessity to oppose the Republican party, who has been trying to restore autocracy since the 1933 Business Plot failed, and FDR implemented the New Deal to prevent Communist revolution (because anything is better than living in cardboard boxes and eating flour paste to live.)

The card / board game Chrononauts expansion The Gore Years imagines an alternative in which the GOP delays of the Florida Recount were not successful, allowing Gore to win, but Andrew Looney posits a result of a Palin administration in 2008. To be fair, he also imagines avoiding WWII (hard to do) might create a period of European peaceful prosperity, so YMMV.

The 2024 election is an indictment not just of Americans but of the viability of democracy in a world where billionaires exists who can create disinformation campaigns that can convince the masses to make uninformed decisions against their own personal interests. In fact, the entire 20th century in the US has been a master class in how to subvert democracy, so even if we were able to reform federal elections (eliminate the EC, insert ranked choice voting or some other non-FPTP election model) elections may continue to be controlled by demagogy and massive propaganda machines.

We don't know (all of) what must be done, but we do know neither US major political parties will willingly relinquish power to move towards public serving government. Considering how much it appears someone is fucking with a time machine to meddle with the past since at least 2000, Frank Zappa may yet live again.
