This is typical for American elections. Voting should be MANDATORY for everyone, but it's usually only old farts and fanatical groups doing it. It's the only way this joke of a country will ever get back to a point where it can be unironically called a democracy.
Perhaps they will care more if they are forced into it. That sort of change will take time, but it will be better for the country. Claiming that some people shouldn't be eligible to vote because they aren't "educated" is a non-stop ticket straight to an oligarchy. If you think it can't get WORSE, you're mistaken. The mob might be stupid, but at least they aren't corrupt. It's easier to manipulate a vote the fewer people there are, and the more regimented and typical elections become. Something as large and important as a Presidential election shouldn't come down to fifty people in a couple of "swing states" which are the cultural and economically LEAST important in the fucking country, but they do anyway because fuck logic.
