 Choosing not to vote in the election will not be taken as a political statement by any politician. I can tell you there's zero percent of candidates that will see that as a protest. They will see it as you don't care and you want to let someone else decide for you. It is much better even if you don't like either of the candidates show up and write in a vote for none of the above or even Mickey Mouse because that showed you caring enough to show up. You cared enough to show up and then you chose someone who was not on the ballot.
