Voting for a 3rd party is not discounting your vote.
If you vote Democrat, great your vote matters. If you vote Republican, again, great your vote matters. IF YOU VOTE FOR ANY 3RD PARTY, YOUR VOTE MATTERS. I am very aware of the infinitesimally small chance that anyone other than Trump or Biden win.
That one vote for neither is one added voice to the rapidly growing population who are frustrated with the unbalanced two party system. Do not feel forced to choose between one or the other because “they can actually win.” With that kind of mindset, other parties will continue to never even have a chance to speak at a debate because votes keep getting funneled to one side or the other. Vote for who you believe in regardless of outcome. Show what actually matters to you. I love you and vote safely.
