I feel like we don't live in a democracy..?

I was watching South Park where they have to vote on a new school mascot- either a giant douche or a turd sandwich. Stan doesn't want to vote because the choices suck but his parents get pissed. I feel like this is how it is in America sometimes. I have no one else to vote for besides Ronald McDonald and The Burger King. How are we finding these people and putting them up to run for our parties? Like really... John McCain and Barack Obama? Is that the best America can do!? What happened to Abraham Lincoln and Kennedy?
