Relational Organizing: talking to everyone you know (who is a Democrat or left of that) about voting
Download the app “Vote Joe” on your phone.  It will go through your contacts and let you know everyone who lives in a swing state.  Then it will show you their voting history.  You can see–for example–who voted in the 2016 Democratic Primary and then did not vote in the General Election.  Call these people.  Tell them you are counting on them to vote in 2020.  Ask about their voting plan.  Keep calling them.

Do FLIP NC’s “Social Voter Program” training for more info about how to persuade people you know to vote and to volunteer.  (They run these trainings frequently.)
