Vice President Kamala Harris and former President Donald Trump will campaign in different parts of the key swing state of Pennsylvania on Monday.

Harris will speak in Erie, located in the northwest corner of the state, around 7 p.m., while Trump will address supporters in the southeastern suburbs of Philadelphia at about 6 p.m.

As the nation’s largest battleground state, with 19 electoral votes, both Democratic candidate Harris and Republican candidate Trump have made regular visits to Pennsylvania.

Last weekend, Trump returned to Butler, the site of a previous assassination attempt, and earlier this week, former President Barack Obama led a rally in Philadelphia in support of Harris’ campaign. Harris’ campaign stop tonight marks her tenth trip to Pennsylvania, while Trump has also recently visited Reading and Scranton.

In Pennsylvania, the most likely state to decide the election, Harris currently has a 0.6 point lead over Trump, according to FiveThirtyEight. Nate Silver’s poll tracker shows her lead in the state is slightly wider, at 1 point. The times’ In the overall poll, Harris leads with 49 percent, compared to Trump’s 48 percent The hill has Harris at 48.6 percent and Trump at 48 percent.

A New York TimesA /Philadelphia Inquirer/Siena College poll of 857 likely voters in the Keystone State showed Harris leading former President Donald Trump, the Republican nominee, by 3 percentage points.

The poll, conducted between October 7 and 10 and published on Saturday, shows Harris with 50 percent of the vote, compared to Trump’s 47 percent. However, Harris’ lead is within the margin of error of plus or minus 3.8 percentage points. Additionally, the poll reported that 3 percent of respondents did not know who they supported or refused to answer.

A Center for Working Class Politics/YouGov survey of 1,000 registered voters found Harris leading Trump in the state 46.8 percent to 44.7 percent. The poll was conducted between September 24 and October 2, with a margin of error of plus or minus 4.19 percentage points.

Although Harris has a marginal lead in the state, some recent polls have indicated that a Trump victory in Pennsylvania is not out of the question.

An Emerson College Poll /The hill A survey of likely 1,000 Pennsylvania voters showed Trump leading Harris by 1 percentage point, with 49 percent of respondents supporting Trump and 48 percent supporting Harris. The poll, conducted between October 5 and 8, has a margin of error of plus or minus 3 percentage points.

According to The Associated Press, the city of Erie has a Democratic majority of about 94,000 residents. Erie is surrounded by suburban and rural areas with a significant number of Republicans. Trump also visited Erie on September 29.

Democratic Sen. John Fetterman of Pennsylvania said he is “thrilled” that Harris is campaigning in Erie. In an appearance Monday morning at CNN newsroom Along with Jim Acosta, Fetterman noted that Trump won Erie County and the state from Democrat Hillary Clinton in 2016, while Biden claimed the county and Pennsylvania from Trump in 2020.

“Erie will choose Pennsylvania, and Pennsylvania will choose the president,” Fetterman predicted. “People discuss how Pennsylvania is a small version of the United States, and Erie is a smaller version of Pennsylvania. It has a rural, suburban and also an urban core.”

Fetterman also predicts another razor-thin presidential margin in the Keystone State.

“It will be close, but the battle for the White House will be won in Pennsylvania,” he added.

The vice president needs 44 electoral votes from the tossing states to secure victory, while Trump needs 51.

Harris’ clearest path to victory next month would be winning the three “blue wall” battleground states of Pennsylvania, Michigan and Wisconsin, barring any shock results elsewhere. Trump’s most efficient path to 270 votes in the Electoral College would be to win the swing states of North Carolina, Georgia and Pennsylvania.

Silver’s latest predictions showed Harris narrowly on track to achieve this, although he said in late September that he believed the vice president’s campaign should be nervous about Wisconsin and Pennsylvania.

Major issues such as Pennsylvania’s energy industry and natural gas fracking are expected to feature prominently in the battle for the votes of the undecided electorate. With mail-in voting already underway, about 7 million Keystone State voters are expected to participate in the presidential race.

Trump’s town hall will take place Monday evening at the Greater Philadelphia Expo Center and Fairgrounds in the suburb of Oaks, aiming to boost turnout among his supporters.

On Tuesday, Minnesota Gov. Tim Walz, Harris’ running mate, will travel to Western Pennsylvania for a series of campaign events, ending with a campaign rally and reception in Pittsburgh.
