This election isn't about greatness, the future, or even Donald Trump. It's about defiance. To his supporters, a vote for Trump is a way to flip the middle finger to the system, the media, the elite, the liberals, the know-it-alls and the people who pretend they're better than us.
Feelings are powerful. According to research, 95% of our decisions are based on subconscious factors - like how we feel. Not logic. Not what you "know" is right. We make decisions based on what we feel in the moment.
Anger is a powerful emotion. What Trump represents is real. Concern about Hillary's ability to fix a system she's been inside of her whole career is real.
Don't talk to the people who agree. Stir emotion in those who don't.
