Nearly every major decision governing the country bears the stamp of the U.S. Senate. Yet, the current makeup of the Senate — which is predominantly white, conservative males — does not necessarily represent the majority of Americans.

Senate insider Adam Jentleson joins Julian Zelizer and Sam Wang in this episode of Politics & Polls, which originally aired as a live virtual event Feb. 22 and was hosted by Labyrinth Books. Jentleson, public affairs director at Democracy Forward and former deputy chief of staff to Sen. Harry Reid (D-NV), is author of "Kill Switch," which shows how the Senate has been transformed over the decades by a minority of white conservatives.
