Elections are all about turnout. Hence, election campaigns mostly aren't about convincing the undecided. They're mostly about motivating and energizing your voters to show up on election day (get out the vote!), and demoralizing and confusing the other side's voters to stay home (you're principled, but your candidate is un-yoursidesian and cannot be trusted).

I'm going to vote, as I always do. I don't need manufactured outrage as a motivator. Unfortunately that is what ad-driven social media and news needs to get eyeballs, so it's all we've got.

I'll sum it up for you:

"Vote for the person we picked for you because they're not Trump."
