"I don't know whatever happened to Avi."
He's a political analyst. Here's a link to audio/video of a panel he was on in October at Boston College, discussing the upcoming election.

How interesting! I met Avi Nelson as a freshman at Boston College in the fall of 1972. He was giving a lecture, and then opened up for q&a. I believe he was 26-27 years old at the time. I was a guest on his show twice a few years later.
