Democratic National Committee Chair Tom Perez says the handful of 2020 presidential caucuses should be the last the party ever holds. He didn’t specifically name Iowa, which for decades has led off the nominating calendar, but his position would represent a seismic shift in the party’s traditions. Perez’s term as chair will end before the 2024 nominating calendar is determined.

But he told The Associated Press on Monday, the opening day of the Democratic National Convention, that he plans to “use the bully pulpit as a former chair to make sure we continue the progress” of changes after the bitter 2016 primary fight between Hillary Clinton and Bernie Sanders.
