Cass Sunstein had a couple of columns on Bloomberg here and here on Whittaker Chambers and the Tea Party (sort of hard to describe, so I’ll just leave it at that). Chambers biographer Richard Reinsch comments here with some additional thoughts.
As for Rand and Chambers, I have found a lot to admire in both of them and they have both influenced me deeply in many ways although I take neither of them in full. But I will add that in my opinion Chambers’s bit about “To a gas chamber–go” may very well be the most unfair, scurrilous thing I’ve ever read. I certainly admire Chambers as a man and as a thinker, but I’ve always thought that one line was so out-of-line that it does make me think less of him.
