Four Democratic debates in, it’s plainly obvious there are two things the media wishes it didn’t have to deal with: climate change and Bernie Sanders.

Let’s start with climate change. “I hope we will discuss it at length tonight,” Sanders, whose climate plan advocate groups have overwhelmingly praised as the strongest in the race, said early on in last night’s debate. No such luck. Last night was the first debate this election where there was not a single question about what is by far the most dangerous and pressing threat to global peace and security.

To put this into perspective, June’s saw four questions on the topic, July’s saw five, and September’s had three (in which one was from a viewer, and another was grist for George Stephanopoulos to ask Joe Biden if Sanders and Elizabeth Warren are too tax-and-spendy and extreme). In fact, the topic was mentioned a mere five separate times last night: by South Bend mayor Pete Buttigieg, billionaire climate activist Tom Steyer, universal basic income advocate Andrew Yang, and, of course, Sanders.
