"Bernie Sanders is back in the Senate minority. Hillary Clinton is selling books and playing with grandchildren. And the Democratic Party is still navigating the fallout from their bitter 2016 presidential nominating fight," AP's Bill Barrow reports.

At issue: "[P]arty leaders failed to agree on how to reduce the influence of 'superdelegates' in picking Democrats' next White House nominee."

• DNC Chair Tom Perez "is promising the party will curtail superdelegates' role at the 2020 presidential nominating convention, but he's been unable to broker a shift he says is needed to avoid charges of favoritism that dogged Clinton."
• What's next: "A ... panel this week opted to delay specific action until this summer. ... [T]he full DNC [today] is expected to ratify a generic commitment to reduce superdelegates' 'perceived influence.'"
