yes you have a great option available to you, and it's something that anyone can do.
accept the fact that you have zero ability to influence nationwide policy, stop acting like earth's mightiest defender whose opinion or vote will somehow make the world a better place, and instead choose to take personal responsibility over the things which you can affect. joe biden, trump, third party, abstain, your vote isn't going to change the outcome. the idea that your vote matters is a scam. and this sword cuts two ways. if your vote between trump and biden does not matter; this implicitly means that the democrats choosing to nominate biden does not affect you. the electoral college is going to choose who they want to. and before that, the vote of thousands of people is going to drown out your voice. you can let it go as easy as that, be happier, be more fulfilled, and still nothing has changed because your vote would not have made any difference.
are there people in your life that you can truly rely on? stop taking them for granted and let them know that you appreciate them. is there a way you can help your local community? help the people that are in front of you right now. are you unsatisfied with your health or diet? start exercising, do research on how to eat better.
this is the stuff that actually matters. federal politics is just a bullshit distraction that allows you to feel virtuous while accomplishing nothing.
