Even the two major opposition parties could not have pulled off a supermajority (67% required for the impeachment) on their own. It helped that the ruling party was split into two factions, one of which sided with the opposition at the last minute.

Now we have four major parties, one minor party, and a bunch of independents who all hate one another. It's going to be fun! At least I hope this will bring some much-needed diversity to Korean politics. Two parties are boring and too easily devolve into an ideological staredown.
