Democrats opened their convention in Chicago on Monday by sending off Joe Biden. And then the president closed the night – which ran significantly behind schedule – with a hand-off to Vice President Kamala Harris.

Biden said choosing Harris as his running mate in 2020 was “the best decision I made my whole career.”

“She’ll be a president our children can look up to. She’d be a president respected by world leaders, because she already is. She’d be a president we can all be proud of. And she’d be a historic president who puts her stamp on America’s future,” Biden said.

His passing of the torch demonstrated the shift for Democrats. The party, which was deeply fractured just last month as pressure mounted on Biden to exit the race, was united Monday night behind Harris – and against her Republican opponent, former President Donald Trump.
