We’re knee-deep in primary season. Super Tuesday is right around the corner, where voters in a dozen states take to the polls. It feels like primaries have been around for as long as there have been elections. But did you know they were actually invented by Teddy Roosevelt? We learn more. WBEZ’s new anchor/host Jennifer White makes her debut on the Morning Shift. She talks to Chicagoans Lee Bey and Rick Kogan to learn about her new city. And the Stritch School of Medicine at Loyola University is the first major medical school in the country to offer a class in Transcendental Meditation. We hear more about the class, why it’s being offered, and how the students are using the TM technique to manage the stress and workload of their demanding educational program.
