So do what I literally said before, build up a party, take places that you have a realistic chance of winning, build your parties power base and then take larger constituencies. That’s how a an organisation actually interested in political power would go about it with multiple years out. Not trying to jump to the highest level office in the land where the mathematical reality of the system insists that that one of the top two candidates will win.
Ah yes I’d forgotten about all those elections in a winner takes all system where a candidate was polling at 1% the day before election turned out to win it. Your obnoxious posting style really helped me remember that absolutely true fact.
So why dont you just vote for yourself? Clearly thats the only way to agree with your candidate 100% and it clearly doesnt matter to you what the odds of winning are.
If you want to get an actual left winger into office in the us you have exactly three options, entryism into the democrat party and pushing a left winger in the primaries (ie bernie, maybe AOC in the future), building up a new party starting by taking local offices in progressive places until the dems either have to pivot to the left or are replaced by you, revolution.
Ignoring reality and voting for a third party in the presidential election is nothing more than posturing at best and actively enabling the worst elements in society at worst.
If you dont understand the difference between trying to start by winning a mayoralty of a town of 10,000 people then some state legislature seat and trying to win the president of the USA without an existing power base I dont know what to tell you. I cant break that down to being any simpler for you as to why starting with the later before you’ve managed the former is pointless.
