This episode contains strong language.  During much of this election cycle, Julius Irving of Gainesville, Fla., spent his days trying to get former felons registered to vote. He would tell them about Florida’s Amendment Four, a ballot initiative that extended the franchise to those who had, in the past, been convicted on felony charges — it added an estimated 1.5 million people to the electorate, the nation’s largest voting expansion in four decades. On today’s episode, Nicholas Casey, a national politics reporter, spends time with Mr. Irving in Gainesville and explores the voting rights battle in Florida. Guest: Nicholas Casey, a national politics reporter for The New York Times.  For more information on today’s episode, visit nytimes.com/thedaily  Background reading: Former prisoners can now go to the polls in Florida.
