Kamala Harris warned a crowd that time was running out at a get-out-the-vote event in Madison, Wisconsin, on Wednesday, joined by a lineup of folk and pop musicians including Remi Wolf, Gracie Abrams and Mumford & Sons.

“We have six days left in one of the most consequential elections of our lifetime,” the vice-president and Democratic nominee told the crowd, denouncing Donald Trump and issuing a dire warning about the consequences of a second Trump presidency.

“On day one Donald Trump would walk into office with an enemies list,” said Harris, before launching into a speech highlighting her policy planks, including a proposal to cut taxes on small businesses and to expand healthcare coverage for families caring for an elderly parent at home. To prolonged applause, Harris rallied the crowd in support of abortion rights, vowing to sign protections for reproductive healthcare into law.

As she has often during her campaign, Harris projected a centrist image, pledging “to listen to experts, to those who will be impacted by the decisions I make, and to people who disagree with me”.

During her speech, protesters in two different sections of the crowd interrupted her to draw attention to Israel’s war in Gaza, shouting “free Palestine” and unfurling banners.

Pausing to address the demonstrators, Harris said: “We all want the war in Gaza to end and get the hostages out as soon as possible, and I will do everything in my power to make it heard and known.” She added, to cheers: “Everyone has a right to be heard, but right now I am speaking.”

Harris has repeatedly visited Wisconsin, a key swing state where elections are decided by the razor-thin margins. She has paid special attention to Madison, and its suburbs, which reliably turn out overwhelming majorities for Democratic party candidates in races that generate unusually high turnout. In the 2020 presidential election, voter turnout in Dane county reached 89%.

The campaign has invested in youth organizing in Wisconsin, hiring seven full-time campus organizers and a youth organizing coordinator. To broad applause, Ty Schanhofer, a first-time voter and student at the University of Wisconsin, introduced Harris and encouraged students to vote early.

“I love your generation, I just love you guys,” said Harris, during the rally, praising young people for being “rightly impatient for change” and enumerating a list of challenges, including the climate crisis and school shootings, that have come to define the gen Z experience. “I see your power, and I’m so proud of you. Can we hear it for our first-time voters!”

The former lieutenant governor Mandela Barnes spoke at the rally too, highlighting the narrow margins that have come to define statewide elections in Wisconsin.

“I want us to feel joy once again,” said Barnes, who ran for a seat in the US Senate and lost by one point to Ron Johnson, the incumbent Republican who has bolstered Donald Trump’s wildest conspiracy theories – including his claims of a stolen election in 2020. Chris LaCivita, a senior staffer on the Johnson campaign, is co-manager of Trump’s 2024 presidential campaign.

The campaign punctuated speeches including Barnes’s with musical acts to rally the crowd.

“We have values and ideas that deserve a platform,” said the singer-songwriter Gracie Abrams, a popular gen Z musician whose performance drew uproarious applause. “Our participation and our vote have never been more crucial.” Abrams was likely a draw for some in the audience, which leaned young tonight.

The campaign also offered the elder millennials in the crowd something of their own: a performance by the British folk-pop band Mumford & Sons, whose lead singer announced to some surprise that he has voted in California, where he was born.

Harris has featured a lineup of celebrity endorsers and performers at her rallies during the 2024 election cycle. In Texas last week, Beyoncé herself appeared to endorse Harris’s presidential bid, and Jennifer Lopez is scheduled to appear with Harris at a rally later this week. The star-studded series of events could give the Harris campaign a boost. When Harris campaigned in Eau Claire, Wisconsin, the folk band Bon Iver – from the Eau Claire area – opened for her.

The Madison crowd was energetic on Wednesday night, but with less than a week to go before election day, some Democrats at the venue seemed anxious.

“I’ve been making calls for Harris,” said Mary Ann Olson, a retired teacher, who waited in pouring rain for the rally. “If she doesn’t win, and I didn’t do anything, I think I would hate myself.”

Olson’s daughter, Chelsea, said she was “really stressed out”, adding: “I’m not sure I can handle four more years of Donald Trump.”
