On the third, and final, installment of That’s the Ticket, Dan and Alyssa talk about what factors a candidate has to consider once they’ve vetted potential VPs, how the vice presidential announcement process has evolved over time, and finally who they think Biden will pick. Dan also talks to Perry Bacon Jr., a senior writer from FiveThirtyEight, about what polling does and doesn’t tell us about the impact of a VP pick.
