I guess I’m confused by this response.

Sure just let me know what you need explained.

one should vote for a third-party candidate in this election

Yeah I didn’t advocate for a position. Third parties have historically been pretty insignificant and the idea that they are spoilers isn’t borne out by reality. The identification of, for example, the greens’ in 2016 as spoilers, is so patently absurd, the person making that argument or any argument that follows from probably isn’t worth addressing, because whoever is making it doesn’t know up from down, or even have the basic ability to count. I dont advocate for any particular voting policy or strategy, but rather try an stay focused on the effectiveness of campaigns in terms of what works or doesn’t work. Both major parties are leaving more votes in their respective couch cushions than any modern 3rd party candidate has ever received.
