The four-time Grammy winner isn't the only Biden playlist mainstay helping his campaign against President Donald Trump. Still, Biden has gone beyond celebrities in search of campaign surrogates. Stars generate candidate buzz, help with fundraising and can build campaign event crowds even for those online. His reelection campaign has been holding its own online events with top supporters nearly every night for months and says its online events average 2.6 million views per broadcast, though its headliners are often the presidents children. The Trump campaign has also seized on Biden's preferred venue for participating in online events, a basement studio in his Delaware home accusing the former vice president of hiding from voters.
