There is nothing “democratic” about how the US works if you define “democratic” as “one person one vote”. Because of gerrymandering, the electoral college, 2 Senators per state etc, you have less voting power if you live in California than if you live in Nebraska.

Besides, a government run by the “majority” tends to trample on the rights of the minority. I don’t just mean racial minorities. I mean anyone who holds minority viewpoints.
