Throughout Monday’s presidential debate, moderator Lester Holt did not ask a single question about key issues discussed in the course of the campaign, including immigration and climate change.

Immigration, of course, has been a major feature of the campaign, with Donald Trump scapegoating migrants for a variety of ailments. The very fate of the human population depends on addressing climate change.

Both candidates addressed the issues in passing as part of their answers to various questions, but neither discussed their plans at length. For some reason, Holt did not find either topic worth asking about.
