As a U.S. citizen I can walk into a polling place in a few weeks and vote for whoever I desire. I have done this in several past elections. However, in every case I did not want the person I voted for to be elected into office. I simply disliked them slightly less than their competitor. This got me to thinking, why can't an election allow "negative" votes? As in, why can we not say "no" to candidates but only "yes"?
The most obvious problem I can think of is "What if no one wins?" Well, so what? The office is simply unfilled until a suitable candidate runs for the office and is chosen by the people. This will necessitate repeat elections but I see no reason why this is impossible.
