Bruce Springsteen and Barack Obama attended a rally to support the Harris-Walz presidential election campaign in Philadelphia on Monday. The use of the rock star and Mr Obama highlights how Ms Harris’s campaign is in an all-out sprint ahead of Election Day, leaning on some of the most noteworthy names in the party to both help her deliver her closing message and lambast her opponent, former president Donald Trump. Mr Obama spoke about Mr Trump’s rally at Madison Square Garden in New York one day earlier, specifically criticising that event’s warm-up speakers, including comedian Tony Hinchcliffe, who referred to Puerto Rico as “an island of garbage” during his often vulgar opening set.
