If you spend your vote on a candidate who truly has the nation’s best interest in mind, who will actively bring real, positive, Constitutional change, and who adequately represents the ideals for which you stand, then you have not wasted your vote but rather invested it. I have no common ground with Biden or Trump, that’d be the real wasted vote imo. Edit: The binary choice wants to fight endless wars, make decisions for me, and increase spending.
How will that benefit when they will inevitably get 2% of the vote? Again, if you are further left than Biden, this should be an easy choice, because one candidate will slowly walk towards that goal, while the other will run in the opposite direction, harming millions of people along the way and making it more and more difficult for meaningful change to occur in the future.
