I’m pretty sure I saw Paul Krugman on my NJ Transit train this morning. He was sitting across and two seats behind me in a quarter-full car and was typing on a laptop. I know he’s affiliated with Princeton, and he might have been going there — I was on an express train and Princeton was the next stop after Newark.

I’ve disagreed with stuff he’s written about Clinton and Obama lately, but I wouldn’t have known what to say to him.
