I would argue this is a [consequence of our "choose one" voting system](https://www.youtube.com/watch?v=s7tWHJfhiyo), as people vote against the most popular evil rather than for anyone they like. To fix that I argue we need [Approval Voting](http://www.electology.org/#!approval-voting/cc04) so its always in the voter's best interest to vote for their honest favorite.
