Even if we ever get that again, people will be sorely disappointed because legislation will be too busy fixing damages from the previous administration to make much actual progress. Which will be forgotten by the next election (same as it ever was).
In 2048 Reagan’s ghost will still haunt the country, plus Trump’s ghost too.







They don’t use it everywhere. And even then in the House of Commons (where it is used), out of 650 seats, only one 3rd party (and independents) is in the double digits. 80% of the seats are 2 parties, the same 2 parties that have traded power for the past century.
Some other parts of their government do have other voting methods or even proportional representation, allowing other parties to govern.
They also have recall elections(/no-confidence) and more common prime-minister resignations (and probably tons of other rules that change how political power works), meanwhile we have the Electoral College for the presidential election which further ensures a 3rd candidate can be a spoiler assuming they can even win in 1 state.
