A few brief comments in regards to what Jim Brash says here. I have seen some numbers that suggest that if the votes the Libertarian Party had gotten were added to the totals Trump received ,it would have pushed Trump over the line to victory. I have not see this discussed much. If this is the case, you could well see some Republican Party actions against the LP in 2024.

Jim is making the same point I had made ,that no Green has ever been elected to a governorship ,or to a seat in Congress ,the traditional stepping stones to the presidency. I would say this would be a good measure of success for any third party. I was part of the national GP Disability Caucus for several years. We never accomplished much. I would agree 2000 was definitely the high water mark for the GP. Nader was probably the best candidate we ever had. It was the year I joined the party. I don't beleve the GP ever really recovered from what happened in the wake of Bush v Gore. I was a Green until 2017 ,and in that time, I don't recall ever meeting a single union member. In my one PSL branch ,about 60-75 people, we have two union teachers ,a union nurse, and the head of a carpenters' local.  

I am not surprised Biden won ,any Democrat running against Trump would have won ,but 2020 saw perhaps the most uninspiring group of candidates offered to voters in modern history.ever. The fact the margin of victory was so slim sort of speaks to this.
