Hmm. Possibly.

I predict that California will “go blue” in the presidential elections for at least the rest of my lifetime. Someone who “votes red” in California can say that their vote doesn’t matter, and a reasonable person would understand why they feel that way.

You don’t seem like a reasonable person, or you’re also suffering from some nihilistic delusion, possibly.

The most sure method any of us can individually enact to help to ensure that our favored candidate is not elected is to declare that it doesn't matter, and then just give up and not vote.

This method is literally an example of nihilism.
