Isabelle decided to spend her gap year as a political volunteer campaigning on behalf of Joe Biden. She’s been writing postcards, making phone calls, and even posting on social media. But she worries she’s not making enough of an impact, and is surprised by how many people are convinced their vote doesn’t matter. In this special bonus episode of How To!, we bring on Don Green, professor of political science at Columbia and co-author of the book Get Out the Vote: How to Increase Voter Turnout. He recommends the most effective way to connect with potential voters and convince them to actually cast their ballot. It turns out yard signs are overrated.  If you liked this episode, check out “How To Talk Politics Without Wrecking Relationships.” If you have a question, send us a note at howto@slate.com or leave us a voicemail at 646-495-4001 and we might have you on the show.
