If you aren’t registered to vote, register now, while you’re thinking about it. Encourage family and friends to do the same. One less thing to think about when 2018 and 2020 roll around (or whenever your next local election is)! Once you’re registered, try your hardest to vote in all elections that you’re eligible to cast a vote in, from the smallest local elections to the presidential election every four years. The more that any given demographic reliably votes, the more politicians will value their opinions outside of election years (which is *partially* why older white people seem to have a lock on political influence – they vote really reliably).
Also, educate yourself about the restrictions on voting in your state and what your voting rights are – a lot of states have instituted restrictive voting policies following the gutting of the Voting Rights Act that disproportionately prevent people of color from being able to cast ballots.
Pushing back against these repressive policies and laws will get its own post – it certainly deserves it.
