I think it's ironic that your comment was downoted. The mentality of Americans is warped beyond repair. If you don't think you have a chance of winning, it's not "realistic" or what-have-you, until you get to the lottery... See the sister comment about voting for HC against DT because it's all or nothing.
It's a structural problem with how our elections work. No sense blaming individual voters for chosing "vote with the intent to maybe (but almost certainly not) affect the outcome" versus "definitely do not affect the outcome, but maybe (but almost certainly not) send a message".
You're literally restating the tactic, as if that countermands the truth. There is no change unless the behavior changes, which is at the individual level. Why not dispense with the public altogether, if the individuals don't matter? Just leave it to the political parties?
