Democrats turned to their most charismatic leaders and shifted toward the future on Tuesday, as former President Barack Obama and Michelle Obama, the former first lady, made the case that their party’s ticket represented the best of American values.

While Vice President Kamala Harris and her running mate, Tim Walz, appeared at a rally in Milwaukee, convention goers completed a raucous roll call of the states as they crowded the floor of the United Center in Chicago. With President Biden off the stage and vacationing in California, an upbeat energy seemed to take over the events.

Here are some of the highlights from the convention’s second night:

The Democrats have their stars, new and old — Gretchen Whitmer and Bernie Sanders, Alexandria Ocasio-Cortez and Andy Beshear, Bill and Hillary Clinton.

But on Tuesday, the Obamas proved once again that they can ignite the party like no one else. The crowd gathered in Chicago has shown renewed excitement since the convention began, but nothing brought the fire that their back-to-back speeches did.

Of course, the history-making path that Mr. Obama made to the White House some 16 years ago had special resonance at a celebration for the first Black woman to clinch a major-party nomination in American history.
