Pushing for third party votes days before the election isn’t the way. You’ve got to mobilize during the rest of the year, make moves in more local races, etc.

voting 3rd party is basically putting your vote in the bin

Maybe if the third parties didn’t come out of hibernation specifically for the election, and actually drilled hard on the years between, we’d see something. I hate the duopoly, too. But now is a losing strat.
