The closer the race between Clinton v Trump the less likely people will "risk" voting so called "third party". What people don't realize is the "safe state" reality. Also, in most states you can wait until the results start coming in and then cast your vote. If you live in Hawaii and the race appears headed one way or the other and since that state isn't likely to swing anyway, you can cast your vote at the last minute after an inevitable winner appears likely.
