PHILADELPHIA (WPVI) -- Tuesday is Election Day and Pennsylvania is key in the 2024 presidential election, as its 19 electoral votes offer the largest prize among the swing states expected to determine the Electoral College outcome.
The two candidates deadlocked in Pennsylvania, according to ABC News.
Vice President Kamala Harris and former President Donald Trump made their final pitches to voters in the same parts of Pennsylvania at roughly the same time on Monday. They spent the last full day of the presidential campaign in a state that could make or break their chances.
Now, it's up to voters.

Cleanup is underway outside the Philadelphia Art Museum after Harris' massive Get Out The Vote election eve rally on the Benjamin Franklin Parkway.
It was a star-studded event, with appearances from Oprah, Lady Gaga, Ricky Martin and more.
Campaign officials estimate there were around 30,000 people in attendance.
The Harris campaign's massive election eve rally on the Benjamin Franklin Parkway in Center City drew thousands of attendees Monday night.
Pennsylvania Senator Bob Casey and Philadelphia Mayor Cherelle Parker kicked off the event.
"We are all gathered here tonight, and 248 years ago to be exact, our democracy was born. Despite what we hear from that other guy, remember, we live in the greatest nation in the world," she told the crowd.
"I want to thank you all for being here and what you're doing for our commonwealth and country at this moment. All the work that's being done, all the doors being knocked on -- it's because of your work. And we appreciate that commitment to our country at this critical time," Casey said.
The event, which was right outside the Philadelphia Museum of Art, was just as much a concert as it was a rally.
People came to see the star-studded lineup, including Lady Gaga, Oprah, The Roots, Jazmine Sullivan, Freeway and Just Blaze, DJ Cassidy, Fat Joe, DJ Jazzy Jeff, Ricky Martin, and Adam Blackstone.
To end the night off, Vice President Kamala Harris took the stage shortly after 11 p.m.
"It's good to be back," Harris told the cheering crowd as she walked on stage.
During her speech, Harris made a final push to get people out to vote on Election Day.
"We have one day to get this done, so now we need to get to work and get out to vote," she said. "We have so much more in common than what separates us. And let us remind everyone -- your vote is your voice, and your voice is your power."
"So tonight I ask you one last time, are you ready to make your voices heard?" she asked the crowd, who responded in cheers. "When we fight, we win!"
This event marked the final push ahead of Election Day for the Harris campaign to make its mark in Pennsylvania, a key battleground state.
Sen. JD Vance delivered his closing message to the voters of Newtown, Pennsylvania, on Monday, advocating for former President Donald Trump to be elected back to the White House.
Vance told the crowd that the only way the country would get a person who is fit to be president is by voting for Trump.
"So tomorrow, we're going to say to Kamala Harris, you are fired. We don't want you in the White House. We don't want you in the Oval Office, we don't want you anywhere near the halls of power," the vice presidential candidate said.
Vance again brought up the recent "garbage" comment controversy, falsely claiming Harris called Trump supporters "garbage."
"So, to Kamala Harris, you shouldn't be calling your citizens garbage. You shouldn't be criticizing people for daring to criticize you for doing a bad job. And our message to the leadership, to the elites of the Democratic Party -- the people of Pennsylvania are not garbage for struggling under your leadership. But tomorrow, the people of Pennsylvania are going to take out the trash in Washington, D.C., and we're going to do it together," Vance said.
Harris is effectively tied with Trump among likely voters in an Ipsos national poll published Monday evening.
If the election were held today, half of likely voters said they would vote for Harris and 48% said Trump, the poll found.
When American adults were asked which candidate has a better plan, policy or approach to the following issues, Harris led on health care and political extremism, while Trump had more support for the economy, immigration and war/foreign issues, the poll found.
The poll was conducted Nov. 1-3 and has a margin of error of +/- 3.4 percentage points for likely voters and +/-3.0 percentage points for American adults.
