It's usually not smart to argue with strangers at the gym, but I tried to respond, saying that even if you don't like Obama, at least he's done a lot, including the 2009 stimulus package, the Affordable Care Act and Dodd-Frank. Before I could add to the list, he cut me off: "That's small stuff, and anyway, he hasn't done anything on the environment." I pointed to air pollution regulations, including controls on greenhouse gases. He looked at me as if I had missed the point and said, icily, "Just wait until Bernie gets in there."
