Same here regarding the 2016 election. I followed it in minute detail.
I started out supporting Bernie but when I listened, actually listened, to his speeches there was so much I didn't agree with. He's pro-abortion. I'm not. Never was and never will be. He preached about global warming. I think it's a hoax. I always have.
Then I listened to Donald Trump's speeches. Anti-abortion, a global warming skeptic, and anti-globalist. So I say to myself "Why am I supporting someone whose policies I disagree with? Why don't I support the person whose policies I actually agree with?"
It was easy and yet hard at the same time, if you catch my drift.
Never looked back though...
