I wrote yesterday about the premiere of Divided States of America, FRONTLINE’s four-hour series examining the Obama presidency and the country’s deepening polarization.

Our series continues tonight at 9 p.m. EST/8 p.m. CST on PBS (check your local station listings) and online.

To make Divided States, filmmaker Michael Kirk and his team conducted dozens of interviews over hundreds of hours. They spoke to top White House officials, members of Congress from both parties, experienced reporters and other key experts.

At FRONTLINE, we have a tradition of publishing extended interviews from our films on our website. For this project, we are featuring 21 transcripts of some of the most insightful interviews.

We’ve also launched a collection of oral histories on three key themes in the film: the GOP’s opposition strategy, race in the Obama era and Trump’s battle with the GOP.

Together with Divided States itself, it’s a revealing collection of reporting on our politics and the nation that Donald Trump inherits as president on Friday.

P.S. The story continues next week, when we’ll bring you Trump’s Road to the White House — the inside story of how Trump won the election.
