I encourage you to reconsider and vote for whatever you perceive to be the least of all evils. Voting is relatively easy and doesn’t require much effort. It’s literally the least you can do. Yes, may not matter in the end, but it can still inform certain statistics that can be used to support various messages and arguments down the line. If you don’t vote at all, you guarantee you have no impact. Don’t throw away the little power you have.
Even if this does end in political violence or civil war, if you vote, at least you will have tried to avoid that fate by participating in our democracy as much as possible. Voting is just so easy to do, how can you justify not doing it as anything but laziness? It can’t hurt and takes almost no effort.
