Picture a Californian voter who votes for the national majority party. Her House member, her two senators, and her presidential electors are all in the minority. In Canada's 39-percent scenario, that bad outcome at least produces a government that owns the next election. In the US, the Senate filibuster lets 41 senators from states representing under 10 percent of the population hold every policy hostage. That's a minority veto, not a check. Game-theoretically, Canada's majority government faces a simple accountability equilibrium: pass something, get judged, get fired. The US equilibrium rewards obstruction, because voters can't tell who actually blocked what. That's worse.
