Once a radical, always a radical.
He admits to nostalgia for his former radicalism, here:
Jacobin, founded in 2010, is a Marxist quarterly that has gotten notice as the voice of youngish radicals. I took a subscription last year, wanting to know the thinking of the anti-establishment left. As a college student in the early 1980s, I was for a brief period the campus organizer of CISPES, the Committee in Solidarity with the People of El Salvador. I’ll leave it to the historians to determine whether CISPES was a front organization under Soviet control, but I can report that my participation in meetings put me in touch with hard-core communists. So I enjoy a certain nostalgic pleasure when I read the occasional essay that speaks of “objective conditions” and “a working-class vanguard.”
