Colin Quinn has just released two new one-man shows — Unconstitutional on CD, and The New York Story on Netflix. We could use a dose of him right now. I’ve interviewed him a few times for the Boston Globe and always found him a reasonable observer of unreasonable times. He’s bemused by politics and what it does to people. When he came to Boston in 2013 with Unconstitutional, we talked about the show, and also about how partisan America is and probably always has been. This is an excerpt from that conversation.
