The Brennan Center for Justice has a TON of good voter information, https://www.brennancenter.org/ and, if you don't already have one, organize a chapter of the League of Women Voters. Democracy better when they're involved.
The American Association of University Women has a how-to on organizing a voter registration drive or just sitting outside Wal Mart with a folding chair and a card table. https://www.aauw.org/resource/organize-a-voter-registration-drive/
VOTE BLUE like your life depends on it.
On ALL levels.
