As a qualifier, this is mostly advice toward cis white folk/family.

PoC communities face a lot of voter disenfranchisement, so make sure everyone is registered to vote, go together to the polls, have required documentation/ID (fuck voter ID laws), and empower everyone to vote out all the racist garbage currently in power.

White folk, use your privilege to protect them at polls and call out racist poll workers. See Something Say Something (ACLU Justice App is great.)
