Everyone who is eligible should vote. Our founding fathers fought many wars to earn you that right. In short, you are insulting them and our country for ignoring the privilege. Do you know how many people in other countries would and do kill for this right!?!? I am not old enough to vote yet but I still actively follow politics and go to many political debates. I discuss the candidates with my friends and family, because I actually care what happens to America. People these days have no idea how lucky they are to live in a country that holds free elections. It's really quite depressing.
One person with the idea that "my vote doesn't matter so I don't give a sh*t about voting" isn't a big deal. But when over half the population thinks that sh*t gets real.
It's true that you, as an individual, don't make a difference but most people think that, so most people don't vote and if they all voted that really could drastically change the outcome. So always vote, and always encourage others to vote.
i think everyone should vote, even if they just write on the paper that none of the above get their support. people have fought for democracy for years, and many people are still denied that right, so I don't understand why people who get the chance to vote wouldn't.
