I have never missed voting in an election since I was old enough to vote.
We have voted by mail for the last 30 years.
Voting is one way we can make a difference. If you don’t vote, you have no influence on what happens. Zero.
You might not like the candidates, or propositions, but sometimes voting against something worse, is still better than not voting at all. We don’t have a perfect system, but if you don’t vote, you are part of the problems that you don’t like.
“Protest” votes, or not voting, is the same as voting for the side you don’t like. It’s just that people who you don’t respect are the ones who end up making the decisions that we all have to live by (or endure) depending on your perspective.
