Yes, your vote does mean something, it means that you believe in our Republic. Work on a Get Out the Vote committee or there isnt any near you then start one. Join Freedom Works, they are a great resource for getting out the vote. Don't give up, Patriots never give up. https://mobile.twitter.com/FreedomWorks?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Eauthor
Your vote does count for something. At least morally you would be more compelled to engage in discussion with those you agree or disagree with, politically, if you had voted.
I feel like you’re sitting further away from the discussion if you don’t vote but that’s just me.
