Anecdotal but ive heard when people started to realize that Hillary was doing bad at 9-10 Eastern PM, some bernie supporting type voters who said they would stay home because Cali was very safe blue went out to vote even though she was guaranteed the state's EV's because they wanted to "have their voices heard" in the last minute.
