Presumptive Democratic nominee Joe Biden is leading incumbent Republican Donald Trump by 6 points in the critical battleground states of Pennsylvania and Wisconsin, according to the latest polls from CBS/YouGov.

The surveys show Biden at 49% support in Pennsylvania, with Trump at 43%. Biden has 48% support from likely voters in Wisconsin, with Trump has 42%.

Pennsylvania and Wisconsin are considered crucial for both campaigns in 2020. The combined total of 30 electoral votes could swing the election to either candidate. Despite trailing in polls in 2016, Trump upset Democratic nominee Hillary Clinton in both states. Trump edged Clinton by a 0.72% margin in Pennsylvania and a 0.77% margin in Wisconsin.

Trump’s handling of the COVID-19 pandemic may be hurting his reelection chances with swing voters. The majority of registered voters in both Pennsylvania and Wisconsin believe Biden would do a better job of dealing with the outbreak, and are turned off by how Trump handles himself personally.

Biden spent the first 10 years of his life in the working-class city of Scranton, Pennsylvania, and is hoping his ties to the state will help him land a victory there. In Wisconsin, Biden is landing high-profile endorsements from figures such as Gov. Tony Evers and potential running mate pick Sen. Tammy Baldwin, D-Wis.

Recent general election polls show Biden leading Trump. A Georgetown University survey released Monday shows Biden with a 13-point lead nationwide, 53% to 40%.
