No offense, but why do people still think this matters? The US is not a democracy, it’s a republic of democratic states and this is by design. If you want the country to be a democracy, destroy or amend the constitution and remake the country.
The U.S. is indeed a democracy, but it is not a direct democracy. It shouldn't be used as an excuse to wheel in a bunch of tyranny.
The House of Representatives has 435 people. The size used to change after each census but they stopped increasing it early in the 20th century. This makes the system less democratic than it originally was and favours less populated states. The electoral college is based on the number of representatives each state has do it is also less democratic than it used to be.
