“What Can Election Polls Really Tell Us?”

Since announcing yesterday that he would end his campaign for re-election, Biden has endorsed Vice President Kamala Harris to replace him on the ticket. She's not the official Democratic nominee yet. One critical test that could earn her the support of fellow Democrats is polling data.

We're joined by a history professor at the University of Illinois Urbana-Champaign and the director of the polling institute at Monmouth University to answer these questions.
