This isn't a democracy, this is a republic. While we have some power in who we elect, those elected are representing us, and can choose to vote how they want. Whether that screws them in future elections is another story.
This is false. The United states is a representative democracy, AND a republic. A democracy can be direct (As in parts of ancient Greece), or representative (As in... Every democracy that is not in ancient Greece.)
The only criteria for being a republic is that you don't have a monarch. The USSR was a republic. China is a republic. Canada is not a republic. Yet, Canada is also a representative democracy, while neither China, nor the USSR are.
