Well, in the current political climate, it would be both useful and patriotic to express his opinion whether any of the present candidates meet his criteria.
I recall the "Free Speech" movement at UC Berkeley during the 1960s led by old school "Liberals," and I recall the Skokie case advanced by the ACLU.
The dem party has been mainly taken over by progressivism, neo-liberalism, anti-free speech, Postmodernism, intersectionality, at the behest of SJWs.
Hardly anobody on the left besides Dersh says a word.
The Intellectual Dark Web (IDW), is mainly made up of people that are pushing back against this neoliberalism on campuses and the public media.
By the way, some from the old left are now calling themselves "classic liberals," or libertarians.
Professional educators have largely caved to the loud SJWs.
I believe it is widely believed in the Anglosphere is is dragging their left causes into a losing situation.
Losses in November might wake them up. But it is doubtful. Too close to Obama.
