Ask HN: What can we build to help increase voter turnout?
Some ideas that very quickly come to mind (I'm sure you can come up with much better):
1. Pair accountability: match up with a random person, each making sure their counterpart votes (e.g. similar to https://www.stickk.com).
2. Dashboard with people pledging to vote, with drip emails to keep registered users engaged, and gamified to increase "points" by how many unique number of people someone has brought on the platform.
3. Send-a-postcard (e.g. with lob.com) to friends that may be at risk for not voting. Not paid by any campaign/SuperPAC. Paid and sent-by someone they know.
