Ok first of all, you're coming off like kind of a dick, so maybe like, don't.
But the principle of democracy is that everybody of age have a vote. Same as in other democracies.
Oh but that's the really fun part, the US doesn't have that. The EC that other person was talking about the the Electoral College.
See, the founding fathers thought that hey, even though the only people who vote are land owning white dudes, what if those yokels want to vote in someone bad? So they made the Electoral College. Basically each state has a certain amount of, well, guys, who aren't really chosen by the voters, and they cast the vote for President. The more people in the state the more people that are in the electrical college.
In theory they could go against what the voters want to prevent a fascist from taking over, but usually they just rubber stamp whatever the population of their state votes for as a majority.
This causes some real tricky math, so some states have more influence over the election than others, and, sometimes, someone can lose the "popular vote" (how the citizens actually voted) and still win the presidency because they won the EC votes in the right states.
Basically this is why Ohio secretly controls the global powers.
