Vice President Kamala Harris’s ascent to the top of the Democratic ticket has transformed the U.S. presidential race. But the real test awaits: Will the party be able to translate that energy into a winning coalition of voters in November?

Reid J. Epstein, who covers politics for The Times, discusses a group of skeptical voters in swing states who may post the biggest challenge to the vice president. Our audio producers — Jessica Cheung and Stella Tan — traveled to Wisconsin to speak to some of them.

Guest: Reid J. Epstein, a reporter covering politics for The New York Times.
