Super Tuesday is the single richest delegate day in the 2020 primary season. Fourteen states will vote, and the biggest prizes are California and Texas. In the public radio special “Countdown to Super Tuesday,” we’ll hear from journalists, experts and voters from those states, receive updates from NPR’s election team and key party strategists, and tackle the major storylines developing ahead of March 3, 2020. “Countdown to Super Tuesday” is a joint production of KERA’s “Think,” KQED’s “The California Report” and public radio’s Texas and California newsrooms.
