Too bad we can't bring the Soviet Union back. They didn't have to deal with those pesky voters who obviously broken the American system so badly.

That was the entire reason the Constitution was written the way it way, to protect us from the tyrant of the majority. The system's flaws are a feature not a bug.

I'm sure history might paint a clear picture of the hell that situation can bring.
The less the government agrees with each other, the less opportunity for them to cause harm to the citizens.
