That's the Ticket Episode 3: The Decision

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.
