Voting is the only way to ensure our democracy works - making a choice for the candidate who best serves our ideals. For those who cynically say "When you choose between the greater of two evils, you're still choosing an evil"...we have Libertarian, Green, and other candidates. Even if your vote is for someone with no chance of winning, you're still making your voice heard.
For those who claim our system is "broken"....the main reason why is that you're not willing to participate.
Get out. Vote your conscience.
Be an American.
