Make a Plan to Vote:

Primary elections are happening in most states now through September to decide who will appear on the November 3 midterm election ballot. This year, all 435 U.S. House seats, 35 U.S. Senate seats, and many governor, mayor, and state legislative races are up for election. Here’s how to get ready to vote in your state’s primary election.

How do I make a plan to vote?

1. Check or update your voter registration (especially if you’ve moved or changed your name)

First, register to vote or check and update your voter registration. Depending on where you live, you can either register to vote online, by mail, or in person at your local election office. Some states offer same-day voter registration when you arrive at the polls during early voting periods or on Election Day. See our list below for online voter registration deadlines for the primaries by state.

If you’re thinking about skipping this step because you think you’re already registered – think again. There are plenty of reasons to double-check your registration, including:

  • If you recently moved or your address has changed
  • If you legally changed your name
  • If you had your voting rights restored
  • If you haven’t voted in a couple of years
  • If you have 3 minutes to spare and you plan on voting in this election

Double-check your registration just to be sure. Better safe than sorry!

2. Learn what’s on your ballot

There are elections for U.S. representatives, U.S. senators, governors, state legislatures, ballot measures, and other local and state offices happening across the country that have a HUGE impact on your everyday life.

Take some time to learn about the candidates and issues on your ballot, because voting isn’t a pop quiz. Knowing what’s at stake ahead of time ensures you’re prepared when it comes time to vote.

4. Decide when and how you’ll vote

States have varying options for how, when, and where you can cast your ballot. Check your state’s voting methods and choose the one that works best for you. Depending on where you live, you may have several options:

Some states require voters to show a valid ID for in-person voting, so before you head to the polls, make sure you have everything you need.

Why is voting important to fight climate change?

Our biggest environmental challenges require political solutions. Our vote is our power to fight for those solutions.

From the local to national level, our government can have a huge impact on the climate crisis – for better or for worse. The communities most impacted by the climate crisis must have a voice in choosing leaders who can fight for them.

In fact, our vote is so important that the Trump administration and its allies in Congress are staging a massive year-long string of attacks on voting rights. Through their “SAVE Act 2.0” bills, fights in the Supreme Court and more, they are trying to make it harder for millions of citizens to register to vote and have their vote counted on Election Day.

This election season, it’s more important than ever to vote for candidates who will fight for our rights.
