It's a losing formula, all in all. I remember reading them and being excited by what they said. Then I'd read the references. And every time I came back to the journal, I'd moved further and further left until it was redundant and so obviously at odds with what it professed to be. It only works with those who don't dig deeper. So they either make Marxists out of libs and lose them as readers or keep liberals reading and lead them down a dead end.
