Voting is like speeding and being stopped by the police. Imagine driving your car at 100 miles/hour on Commonwealth Ave and being stopped by a policeman. One option you have is to acknowledge what you have done and pay the fine. This is like voting for the less evil candidate. There’s also one option that you could argue with the policeman that you didn’t speed and reject paying the fine. This could lead to a worse situation. That is like voting for a greater evil candidate. Then there is another option: restart the car and drive away as fast as you can. Since you know that the prior two scenarios are definitely going to lead to bad endings, you are trying to prevent them from happening. However, the chance that the police catch you is nearly 100 percent, and you will get into big trouble. Everyone has loss aversion, but it is never a clever choice to believe in a small probability event. The best option is to choose the less evil and minimize the loss.
