Rhode Island Senator Lincoln Chafee

Lincoln Chafee, former U.S. senator from Rhode Island, was often called the most liberal Republican in the Senate. In office, he bucked his party on a number of hot-button issues, including same-sex marriage and the war in Iraq. His book Against the Tide challenges the Republican Party on its rightward drift.

New York Times political reporter Robert Draper says the Republican party's embrace of lies and conspiracy theories has opened the door to fringe actors, who have become among the party's most influential leaders. He points to Georgia Rep. Marjorie Taylor Greene as a prime example of the party's extreme new direction.

As a Republican operative, Tim Miller worked with extreme right-wing media outlets and fed the populist outrage that helped radicalize much of the GOP voter base. His new book is Why We Did It.
