As Bernie Sanders Surges Ahead of Iowa Caucus, DNC Under Fire for Changing Rules to Help Bloomberg

The Iowa caucuses take place today, kicking off the official start of the 2020 presidential election season. Democratic presidential candidates spent the weekend making last-minute pitches to voters at rallies across Iowa. Meanwhile, the Democratic National Committee is facing criticism for overhauling its rules, opening the door for billionaire former New York Mayor Mike Bloomberg, who is running a self-funded campaign, to take part in the next debate. This comes as fear is growing among some Democrats that Bernie Sanders might win the nomination. Politico reports a small group of DNC members have begun discussing a proposal to increase the role of superdelegates to give the party establishment more say in who becomes the nominee. From Des Moines, Iowa, we're joined by John Nichols, The Nation's national affairs correspondent and host of the podcast "Next Left." He's covering the Iowa caucuses on the ground and recently wrote the piece "The DNC's Move to Accommodate Bloomberg Stirs Outrage in Iowa."
