Most important thing: show up on November 8th. Stop looking at polls: no one and I mean NO ONE knows what’s going to happen. My spidey sense is it’s roughly tied. Do I *know* that? Hell no.
Show up and bring others with you.
If you’re in a swing state, get with the campaign and volunteer to knock on doors. If not in a swing state, volunteer to phone. All you need is a computer and cell phone.
