Democrats are on track to have more power in the next Congress than they’ve had since 2009. How can they navigate the divides in a party that now stretches from Abdul El-Sayed in Michigan to Adam Hamilton in Kansas? How do they prevent all their new voters in this election from flipping back in the next one? Can they turn this victory into a springboard to an even bigger and more durable Democratic majority in 2028 and beyond? We will have two episodes that try to answer these questions from different angles, one from the center of the party and one from the left. First, representing the more center view, we have Adam Jentleson, the founder and president of the Searchlight Institute, a Washington think tank. Jentleson is a veteran of the Senate; he served as deputy chief of staff to the former Senate majority leader Harry Reid and chief of staff to Senator John Fetterman. He’s also the author of two books, “Kill Switch: The Rise of the Modern Senate and the Crippling of American Democracy,” and  “Supermajority: How Democrats Can Build Lasting Power,” which came out in September.
