WILKES-BARRE, Pennsylvania (Reuters) – Republican Donald Trump and Democrat Kamala Harris will hold dueling campaign events this weekend in Pennsylvania, the political battleground that may be the most critical state in the Nov. 5 presidential election.
Trump, the former president, will hold a Saturday rally in Wilkes-Barre in the northeastern section of the state. Vice President Harris will conduct a bus tour of western Pennsylvania starting in Pittsburgh on Sunday, ahead of the Democratic National Convention kickoff on Monday in Chicago.
Pennsylvania was one of three Rust Belt states, along with Wisconsin and Michigan, that helped power Trump’s upset victory in 2016. President Joe Biden, who grew up in Scranton, Pennsylvania, flipped the trio back to Democrats in 2020.
The three states are true bellwethers – the only U.S. states to have voted for the eventual winner of the presidential race in every cycle since 2008.
With 19 electoral votes out of the 270 needed to secure the White House, compared with 15 in Michigan and 10 in Wisconsin, Pennsylvania may be the biggest prize in November’s election.
A statistical model created by Nate Silver, the election forecaster, estimates that Pennsylvania is more than twice as likely as any other to be the “tipping point” state – the one whose electoral votes push either Harris or Trump over the top.
Harris’ entry into the race after Biden ended his reelection bid last month has upended the contest, erasing the lead Trump had built during the final weeks of Biden’s shaky campaign. Harris is leading Trump by more than two percentage points in Pennsylvania, according to the poll tracking website FiveThirtyEight.
Trump won Pennsylvania in 2016 by around 44,000 votes, a margin of less than one percentage point, while Biden prevailed by just over 80,000 votes, a 1.2% margin.
Both campaigns have made the state a top priority, including blanketing the airwaves with advertisements. Of the more than $110 million spent on advertising in seven swing states since Biden dropped out in late July, roughly $42 million was spent in Pennsylvania, more than twice any other state, the Wall Street Journal reported on Friday, citing data from the tracking site AdImpact.
Democratic and Republican groups have already reserved $114 million in ad time in Pennsylvania from late August through the election, more than twice as much as the $55 million reserved in Arizona, the next highest total, according to AdImpact. Those figures are sure to increase, given the Harris campaign has not yet made any reservations past Labor Day on Sept. 2, according to the firm.
Both Trump and Harris have visited the state more than half a dozen times each this year. Trump was injured during an assassination attempt at his rally in Butler, Pennsylvania, on July 13.
He has said he will return to Butler in October, and also announced he will give remarks on the economy at a campaign event in York, Pennsylvania on Monday. Trump’s running mate, Senator JD (NASDAQ:) Vance, will deliver remarks in Philadelphia that day as well.
Trump’s trip to Wilkes-Barre on Saturday in Luzerne County is aimed at solidifying support among the white, non-college-educated voters who lifted him to victory in 2016. The blue-collar county voted Democratic for decades before swinging heavily toward Trump in 2016, mirroring other similar regions around the country.
Harris and her running mate, Minnesota Governor Tim Walz, will make multiple stops across Allegheny and Beaver counties on Sunday, the campaign said. The tour is the first time Harris, Walz and their spouses have campaigned together since their first rally as a presidential ticket in Philadelphia earlier this month.
Pennsylvania was at the heart of Biden’s winning 2020 strategy across the Rust Belt states: limiting Trump’s margins among working-class white voters while building majorities among suburban voters and driving higher turnout in urban areas with large Black populations.
The Harris campaign is pursuing a similar “win big, lose small” strategy, aiming for large margins in the cities and suburbs of Philadelphia and Pittsburgh, while limiting losses in smaller counties like Beaver County, where Trump won 58% of the vote in 2020.
