Beware confirmation bias with the 2020 presidential race

“The next debate is do or die for many Democratic hopefuls.”

Andrew Yang “is on fire.”

Elizabeth Warren is “surging.”

“It’s a three-way race.”

I’m betting you can think of a long list of other things you’ve heard on television or read in print to explain what is going on in the presidential race. Many of them will need to be revised eventually. I’ve written often over the years — and even this cycle — that you shouldn’t believe the hype, so I don’t need to warn you about that again, right? …

But the most astonishing thing so far about the coverage of the 2020 race is the lack of major media polling in the handful of key states that are likely to decide the election. Do we really need another national poll that shows how unpopular the president is or that the national Democratic race is stagnant? What we should be getting from the major media are high-quality surveys in Pennsylvania, Wisconsin, Michigan, North Carolina, Florida and Georgia. CONT.
