Zev Yaroslavsky, director of the Los Angeles Initiative at UCLA Luskin, spoke with KCAL9 News following the Democratic presidential debate in Des Moines, Iowa. Yaroslavsky observed that the fireworks that some had expected between Sens. Bernie Sanders and Elizabeth Warren did not materialize. “Neither one of them had an interest in beating up on the other,” he said, noting that some candidates who had previously launched personal attacks are no longer on the debate stage. The six who did qualify — former Vice President Joe Biden, former Mayor Pete Buttigieg, Sen. Amy Klobuchar, businessman Tom Steyer, Sanders and Warren — debated foreign policy, healthcare and trade. Yaroslavsky predicted that no clear winner will emerge from the Iowa caucuses, less than three weeks away, or perhaps even from subsequent voting in New Hampshire, Nevada and South Carolina. “It’s a very close race,” he said.
