In effective two party systems, votes cancel each other out. If I vote A and you vote B, then our votes effectively negate each other. This is why 'strategic voting' is a thing - a problem that does not exist in more sane proportional systems with more diverse representation. The same thing would happen all the way up. Imagine we have two parties, again A and B, that are completely mutually exclusive - one representative always voting exactly the opposite of the other. And now imagine we have a state Massivefornia that has 1 billion voters and a proportional number of representatives, but it's split exactly 50/50. And then there's the other state, Lonely Island, with exactly 1 voter and 1 representative (who... I guess would be one and the same?). In this example, Lonely Island would decide each and every action that goes forward as Massivefornia and their 50/50 split of A/B cancels itself out on everything.
