That was a good interview and I agree with pretty much all of it. The only issue I have is they didn't really get into why Biden won instead of why the progressives lost. Grunwald kind of addressed an adjacent point early in the interview, but if your would have replaced Joe Biden with another sturdy, known moderate without a close tie to Obama, someone like Tim Kaine, one of the progressives win. I don't think the messaging was the issue. The exit polling data and Biden's move left prove that the country is ready to move left as well, but Biden being a comfortable, but well worn blanket, carried the day.
