WATCH LIVE: Trump speaks at a civic event in the Philadelphia area

HARRISBURG, Pa. (AP) — Vice President Kamala Harris and former President Donald Trump will fight their fight for Pennsylvania on opposite ends of the state on Monday, with Harris speaking in the northwest corner of Erie and Trump in the southeastern suburbs of Philadelphia.

The event is scheduled to begin at 6:00 p.m. EDT. Watch it live in our player above.

Democrat Harris and Republican Trump have made regular appearances in the country’s biggest battleground state – it will be Harris’ 10th visit to Pennsylvania this campaign season, and just last week Trump made stops in both Scranton and Reading.

Pennsylvania’s energy industry and natural gas fracking are likely to be issues as they compete for the share of the state’s voters who have not yet made up their minds. Postal voting is in full swing in the state, where around 7 million people are expected to cast their votes in the presidential election.

On his way to the presidency in 2016, Trump beat Hillary Clinton in Pennsylvania by more than 40,000 votes, but four years ago Scranton native Joe Biden beat Trump in the state by about 80,000 votes.

Harris will hold a rally in Erie, a Democratic-majority city of about 94,000 residents that borders suburbs and rural areas with significant Republican populations. Erie County is often cited as one of the state’s most reliable flagship regions, where the electorate has a decidedly moderate voting record. Trump visited Erie on September 29th.

Harris plans to speak about early voting during her rally. And she will stop by a Black-owned small business in Erie before the rally to promote her proposals to give Black men more economic opportunities and other chances to thrive as Democrats try to strengthen the voting bloc.

Trump plans a town hall at the Greater Philadelphia Expo Center and Fairgrounds in suburban Oaks on Monday, hoping to boost turnout among his supporters.

Pennsylvania and its 19 electoral votes, the most of any swing state, have attracted by far the most attention compared to the Democratic and Republican presidential campaigns. Including Monday’s scheduled events, they will have made 46 stops in the state, according to the Associated Press’ tracking of the campaigns’ public events.

Michigan, with 33 visits, and Wisconsin, with 29, are the second most visited states, showing that both campaigns are focused on winning states that were part of the Democrats’ so-called “blue wall” until Trump emerged as the Republican standard-bearer.

Democrats have won three straight gubernatorial elections and both current U.S. senators are Democrats, but the state Legislature is sharply divided.
