Kamala Harris has insisted she has momentum and will ‘win’ the presidential race as rival Donald Trump sells out Madison Square Garden for a massive rally by his loyalists.

The Democratic nominee spent a low-key day in Philadelphia, courting minorities and young voters. He visited an African American church, barbershop and bookstore. Then he stopped by a Puerto Rican restaurant.

Harris, who had previously described herself as an underdog, used a new tone and said that she would win the presidential race.

‘We have a lot of hard work ahead of us, but make no mistake, we will win,’ he told a cheering crowd of 3,000 at a community centre.

‘We will win because if you know what you stand for, you know what to fight for.’

Polls show the presidential race is essentially tied, which means every campaign needs to make sure it gets as many voters as possible on November 5.

Kamala Harris spent Sunday campaigning around Philadelphia

While Harris was rallying voters in the critical battleground state of Pennsylvania, Trump was in New York, a Democratic stronghold, to speak to a gathering of MAGA fans 20,000 strong.

In Pennsylvania, Trump is ahead in the state polling average, but by just one point, well within the margin of error.

The state can decide the presidential election with 19 delegate votes. In addition to multiple campaign stops, Harris’ campaign has released a new ad called ‘Philly vs. Trump.’

The ad reminds voters of negative comments the former president made about the city. The ad will air during Sunday’s football game between the Philadelphia Eagles and the Cincinnati Bengals, which means it will get good airplay.

But Harris has focused her time in the city, a majority Democratic stronghold, on appealing to minority voters and Generation Z and reminding them to use their voices on Election Day.

“Philadelphia is a very important part of our path to victory, and that’s the reason I’m spending time here,” Harris told reporters. ‘But I’m very optimistic about the enthusiasm here and the commitment of people from all walks of life.’

At his rally, he reminded young voters that the choice is theirs on Election Day.

“We have the ability to turn the page on the same old, tired showdown,” Harris said. ‘We are ready to chart a new path forward.’

‘We are a new generation of leadership that is optimistic and excited,’ he said.

‘The great thing about living in a democracy is that as long as we preserve democracy, we the people have the power to choose our direction,’ Harris said.

Harris’ 15-minute speech was interrupted twice by a medical emergency and a protester.

Shortly after he started speaking, someone in the back fainted. Harris paused to allow medical professionals to reach the person.

‘That’s what we’re doing. “We look out for each other,” he said.

A few minutes later he was interrupted by a Gazan protester. He responded in crowd chats: ‘We won’t be back!’

Harris said she was determined to end this war and bring the hostages home, then returned to her speech.

The vice president did not focus his fire on Trump during his remarks. He left this to his representatives.

On Sunday, running mate Tim Walz compared Trump’s Madison Square Garden rally to a Nazi party event held at the same venue in 1939.

Speaking on the campaign trail in Nevada, Walz said: ‘Donald Trump is holding a huge rally at Madison Square Garden. There is a direct parallel to the big rally that took place at Madison Square Garden in the 1930s.

Harris’ husband, Doug Emhoff, also said that Trump was “falling apart.”

“The other side is trying to put out all this noise and public enlightenment and misinformation,” the second gentleman said during a campaign stop in Atlanta.

He then turned his fire on Trump: ‘Just look at him. It’s falling apart. …. Just listen to what he says.’

Emhoff also accused Trump of a “cooling of free speech” as major news organizations, including the Washington Post and Los Angeles Times, decided not to support a presidential candidate.

‘People in the media are afraid to do something because it creates a chilling effect,’ he said. ‘We can’t live like this.’

Harris, meanwhile, had a day of events in Philadelphia, talking endlessly to voters, exchanging hugs and small talk.

Its goal was to increase voter turnout nine days before the election.

At Philly Cuts in West Philly, Harris sat in a chair that is a cornerstone of good fortune for political candidates.

The barbers told him that every candidate who ran for elected office and held the seat won the election.

Harris also visited a bookstore whose shelves stocked books about Africa, civil rights icons and slavery.

She asked for book recommendations for her grandchildren, ages 8 and 6.

“Victory goes through Philly,” Harris reminded people at the stop. ‘It passes through Pennsylvania.’

He also told someone there: ‘I plan to gain some weight after this is over. ‘They work me to my core.’

And at Freddy and Tony’s Restaurant in a working-class neighborhood in Puerto Rico, he continued his message.

‘Nine days and hard work as we know is good business and we win,’ he said.
