‘Electability’ Polls Are Unreliable and Need to Stop

Kamala Harris faced many challenges in her presidential campaign before ending it this month, including doubts that she was “electable.” She wasn’t alone.
Last month, the news cycle was awash with breathless commentary in the wake of a November 4 New York Times UpShot/Siena College poll, published under this provocative headline: “One Year From Election, Trump Trails Biden but Leads Warren in Battlegrounds.” The poll came out as Warren had been surging in the polls to a position challenging Biden’s front-runner status in the Democratic presidential primary for the first time.

Decades of political science scholarship shows that polling helps create narratives that can impact voter behavior, the ability of candidates to raise money, and electability, all of which tie to candidate poll performance in a positive feedback loop.
