The fact that the American political system already seems poised to produce a Trump- Biden rematch in 2024 is quite a serious indictment of that system.

@anneapplebaum Personally I think the fact that the system is incapable of preventing a spread of "safe seats" (political gerrymandering), thus basically disabling voting/democracy completely or mostly.

Trump vs Biden OTOH is not exactly surprising, it's Duveger's law brought to its conclusion.

@yacc143 @anneapplebaum It seems the alternative under discussion is not a possible 3rd-party candidate but Trump vs Harris. And imho, if everything were alright with the US they should now be in a temporary one-party phase.
