Kamala Harris said Sunday that 鈥渘o one can sit on the sidelines鈥� in this year鈥檚 presidential election, capping a day of campaigning across the largest city in the crucial battleground state of Pennsylvania.

鈥淲e are focused on the future and we are focused on the needs of the American people,鈥� Harris said, 鈥渁s opposed to Donald Trump, who spends full time looking in the mirror focused on himself.鈥�

Speaking at a city recreation center, the Democratic vice president singled out young voters, praising them for being 鈥渞ightly impatient for change,鈥� and told the audience that 鈥渢here is too much at stake鈥� in the campaign.

鈥淲e must not wake up the day after the election and have any regret about what we could have done in these next nine days,鈥� Harris said.

Mark Ruffalo and Don Cheadle, two actors who starred in Marvel鈥檚 鈥淎vengers鈥� movies, were at the rally. Harris reminded the crowd that Pennsylvania鈥檚 deadline for early voting is Tuesday, telling them to 鈥済et it done tomorrow if you can.鈥�

Energizing voters in Philadelphia, a traditional Democratic stronghold, is crucial for Harris鈥� chances of beating Republican nominee Donald Trump. If turnout falls short here, she鈥檒l struggle to overcome Trump鈥檚 advantages in Pennsylvania鈥檚 rural areas.

鈥淧hiladelphia is a very important part of our path to victory,鈥� Harris told reporters. 鈥淚t鈥檚 the reason I have been spending time here. But I鈥檓 feeling very optimistic about the enthusiasm.鈥�

Kenny Payne, 62, said Harris is going to win and 鈥渋t won鈥檛 be close.鈥� The Democratic voter said he plays golf with a group of Republicans who say they won鈥檛 vote for Trump again.

鈥淚 think we鈥檒l all be in bed by midnight,鈥� he said outside the recreation center where Harris spoke.

Patrick Boe, 46, said he was confident about the city鈥檚 enthusiasm for Harris, but he acknowledged that his view may be skewed.

鈥淚鈥檓 in a bubble here,鈥� Boe said.

Randyll Butler, a youth basketball coach who introduced Harris, said the election was in the 鈥渇ourth quarter.鈥�

鈥淲e cannot get tired,鈥� she said. 鈥淲e cannot get complacent.鈥�

The Democratic coalition relies on voters of color, and Harris鈥� itinerary on Sunday reflected that focus. She began the day with the Black congregation at the Church of Christian Compassion, where she said the United States is 鈥渄etermined to turn the page on hatred and division.鈥�

Harris drew on the story of the Apostle Paul, who overcame difficulties to spread the word of Jesus.

鈥淚n hard times when we may grow weary in doing good, we must remember the power that works within us, the divine power that transformed Paul鈥檚 life, guided him through shipwreck and sustained him through trials,鈥� Harris said.

W. Lonnie Herndon, the church鈥檚 senior pastor, introduced Harris as 鈥渢he voice of the future鈥� and followed her remarks with a sermon about compassion and how 鈥渟trong people never put others down, they lift them up.鈥�

鈥淲e are going to get out and vote,鈥� he said as Harris listened from her seat in the front row. 鈥淎nd let me be crystal clear. We are not electing a pastor. We are electing a president that will deal with these divided United States, bring us back together.鈥�

Her next stop was Philly Cutz, a barbershop in West Philadelphia. Pennsylvania state Rep. Jordan Harris moderated a conversation with Harris and Black men about improving racial representation in education. A poster of Barack Obama, the first Black president, was on the wall.

鈥淲e don鈥檛 pay teachers enough,鈥� said Harris, who would be the second Black president and the first female president, if elected. 鈥� Student loan debt is an issue.鈥�

Outside the shop, people stood on stoops and lined the sidewalks in hopes of catching a glimpse of Harris. 鈥淭he MVP of the White House!鈥� someone shouted.

Harris visited nearby Hakim鈥檚 Bookstore, which specializes in African American history.

鈥淚t鈥檚 beautiful. It鈥檚 just so beautiful,鈥� she said and asked to see good books for 6- and 8-year-old children, the same ages as her nieces.

Harris joked about her weight with Ann Hughes, the mother of Pennsylvania state Sen. Vincent Hughes.

鈥淭hey鈥檙e working me to the bone,鈥� she said.

After leaving the bookstore, Harris headed to a Puerto Rican restaurant named Freddy and Tony鈥檚, where she thanked volunteers and told them 鈥渨e are going to win.鈥�

She also met with youth basketball players at the Alan Horowitz 鈥淪ixth Man鈥� Center. The coach said the players are 鈥渟tudent first, athlete second.鈥� Harris told them to 鈥渢hink of your brain as a muscle and when you exercise it, it gets stronger.鈥�

Harris has tried to keep the focus on abortion rights in the closing stretch of the campaign, including during appearances with Beyonce and Michelle Obama. In an interview with CBS 亚洲天堂 that aired Sunday, Harris declined to say whether she would support any restrictions on abortion, emphasizing the need to restore Roe v. Wade.

鈥淚t is that basic,鈥� Harris said.

The nationwide right to abortion was overturned two years ago by the conservative majority on the Supreme Court that included three justices nominated by Trump while president.

鈥淢y first priority is to put back in place those protections and to stop this pain and to stop this injustice that is happening around our country,鈥� Harris said.

She also brushed off Trump鈥檚 claim that he would not sign a national abortion ban if elected. 鈥淗e says everything, come on,鈥� Harris said. 鈥淎re we really taking his word for it?鈥�

Harris and Tim Walz, the Minnesota governor who is her running mate, are expected to visit all seven battleground states in the coming days, part of a final blitz before the election.

While Harris was in Philadelphia on Sunday, Walz was campaigning in Las Vegas. On Monday, Walz will visit Manitowoc and Waukesha, Wisconsin, before joining Harris for a rally in Ann Arbor, Michigan, where the singer Maggie Rogers is scheduled to perform.

Harris will be in the nation鈥檚 capital on Tuesday to deliver what her campaign calls her 鈥渃losing argument鈥� in a speech from the Ellipse, a grassy space near the White House. It鈥檚 the same place where Trump spoke on Jan. 6, 2021, when the Republican called on his supporters to march on the Capitol.

More campaign stops are scheduled in Georgia, North Carolina, Pennsylvania, Wisconsin, Nevada and Arizona.
