It is difficult for me to imagine what “personal liberty” is enjoyed by an unemployed hungry person. True freedom can only be where there is no exploitation and opression of one person by another; where there is no unemployment, and where a person is not living in fear of losing his job, his home and his bread. Only in such a society personal and any other freedom can exist for real and not on paper.
They backed Hillary in '16 as well. They have a history of revisionism, iirc.
They didn’t back Hillary Clinton in 2016, but they are backing Biden now.
