"First Past The post voting artificially limits the number of political parties to two. "
Kiiiind of, Canada has fptp as well and we have about 4.5ish competitive parties, Liberal Party, Conservative Party, NDP (“socialist” party), Bloc Quebecois (Quebec focussed party [used to be a sepratist party, but has evolved to just focus on getting more favourable policies for Quebec since separating has fallen out of favour in Quebec), and the .5 would be the Green Party. So we can vote against the main 2 without wasting our votes/effectively voting for the party we hate more. BUT the reason I said kinda is notice I said Main 2. NDP has won opposition a few times (2nd most voted for party nationally), but Only 2 parties have ever been the most voted for in an election, the Liberals and the Conservatives. (Bloc Quebecois has won the provincial government multiple times in Quebec, but obviously has never been a contender for national government)
(Green is .5 because most people know about them, but to my knowledge they have never won even a provincial government, which the other 4 all have multiple times)
Edit: Guess theres a bunch of Americans pissed that they cant blame how fucked their political system is just on FPTP
