This is more likely to happen in local elections, where margins can be close. Democrats defeated a developer locally, by 2 votes. We would have a different township if he had won. My household was strongly targeted by pro-development forces. They lied and were nice. My entreaties held the day. In a sense, we were the deciding margin. 2 votes.
Another reason to vote is how many have died to protect our freedoms. Democracy is always on trial in the world, from the right, from Royalty, from dictators, from cutthroat capitalism. We have freedom because we earned it.
I had a grand uncle I never knew. He was gassed in World War I. Not badly, but the nerve gas ate at the brain over time. He served the last 6 weeks of the war, roughly, and in the windup forces for another 9 months. Gassed. He lived in a veterans home in NYC. Then returned to the private sector as an electrical salesman. Then to a veterans home in PA where he died. He was 36. We never knew this tale, only the NYC part. But records have come online. He died. For America.
Another angle on voting is to not throw away your vote blindly by party label. Understand the issues. You're part of the problem if you know nothing and vote because someone told you but you know nothing about what you're voting for. Votes matter. Judges. Supervisors. Sheriffs. School boards that suppress books. Don't give dictators power. Vote for freedom. Find out who that is on the ballot. It's your country. You hand it on to your kids. It was nice for you. Keep it that way.
