Harris and Biden make first joint appearance since ticket change

Thousands stood in line in the summer heat for the chance to see Mr Biden and Ms Harris speak. Social media video showed hundreds still in line as the venue reached capacity.

It’s the latest in a series of events Ms Harris has hosted that have drawn large crowds of supporters, marking a noticeable shift in energy in the presidential race.

The enthusiasm is showing up in polling data, too. A recent survey from the Cook Political Report suggests Ms Harris is erasing former President Donald Trump’s polling leads in Arizona, Michigan, Pennsylvania and Wisconsin.

Vivian Strong waited three hours to get into Thursday’s event. She hoped to be part of a historic moment, she told the BBC.

“I feel a sense of urgency to actually ensure she gets elected,” she said. “I would hate to have another administration of the other guy.”

Before the president and vice-president took the stage, some supporters led the crowd in chants from Howard University – the historically black university Ms Harris attended in Washington, DC.

Many supporters of the vice-president donned pink and green, the colours of the Alpha Kappa Alpha Sorority (AKA) to which Ms Harris belonged.

Linda Jones, a Howard alumna and a member of AKA, said their shared identity excites her. But she was also eager to see Mr Biden speak.

“I’m happy for President Biden to get something accomplished that he’s worked so hard for,” Ms Jones told the BBC, referring to the prescription drug deal. “He’s such a good man and I felt very bad he was leaving with a cloud, so now I feel [this policy] is one more boost for him.”
