I know it's only August, but I thought I'd start early:
If you have the legal right to vote in the United States, there is no benefit to you in not voting. All that not voting does to you is remove your most powerful legal ability to impact the identity of those who represent you in the government.
By the time you reach the election, by the time ballots are printed and you are filling in a bubble or pressing a button or flipping a lever, your only meaningful choice for who to vote for are the people who are listed on the ballot.
Because we live in a two-party system, in the vast majority of jurisdictions*, you are choosing between members of two parties. If you vote for someone who is not a member of one of those parties, you are throwing away your ability to meaningfully impact who wins that election. It sucks. it's shitty. It's unfortunate. But if you want a third party candidate to have a chance in a major race, it starts years before the election, not when you are standing in front of your ballot in November.
And if you think, they're both the same as each other--they're not. For literally any policy that you care about, there will be differences. Pick the policies you care most about, find the one who sits closer to you and vote for them. That is the only way that laws will move in the direction you want, by electing people who vote for policies that are closer to what you want.
I studied game theory in college, and from my standpoint it was one of the most useful and educational classes I took during my entire academic career, because of this key idea: If you want 10, and your options are 0 or 5, 5 is a better option for you. Something gives you more than nothing, even if you want a lot.
You will not get a politician who agrees with everything you want, unless you run for office yourself. Pick what you care the most about, and vote based on that. See voting as harm reduction. See voting as public transportation. See voting as whatever gets you out to vote.
*There are a few independents in office. An independent or third party candidate will not win the Presidency in 2024.
