The checks and balances the US has have shown themselves to be weak.
Well the system worked, Trump was bounced.
Yeah but only after he was able to do significant damage to the U.S. (including giving state secrets to Russia, engaging in various forms of grift, etc.) If the "system worked", he would have been quickly bounced from power.
If Trump was the PM he could nominate Senators, Supreme Court Justices, handpick a GG friendly to him, choose cabinet, and tell his MP's to vote how he wants our else bounce them JWR-style. Plus no term limits.
True... the Canadian prime minister does hold a significantly greater amount of power than the president (in their respective countries at least). I think it's just been our better-educated electorate that has kept things from getting as bad as they are in the U.S.
