A Civic Hacker Corps

I've always been told, "If You Don't Vote, You Can't Whine." This is a statement I've heard from hundreds of American citizens that I've encountered throughout my life, across every region of this great country. While I agree with the intent of this statement, I have to declare that it isn't enough!
