Dems employed some similar strategies with Sanders in 2016, despite his decision to run as a Democrat.
It is interesting to look at the intersection of positions held by the likes of Ralph Nader and Ron Paul, especially where they differ from their respective “most aligned” mainstream party platforms, where they are marginalized. The most prevalent of these are the Military and Prison Industrial Complexes, and in my anecdotal experience 98% of the people agree regardless of their socio-economic status
To be clear voting third party in anything close to a swing state rather than whoever you feel is the lesser of two evils is not something I would do. I don't think third party voting makes sense in a US (or UK) system beyond being a protest vote, I was just trying to show what happens when a remotely supportable third party candidate emerges.
I don't think trying to shame those who did is going to do much to win them back for more than one election cycle without providing a candidate they can believe in though (somehow a lesson the democrats continue to drag their heels on every single time). Especially when in the case of Florida there were other factors on hand that were far clearer miscarriages of justice which they decided to accept.
