A general election was held in the U.S. state of Pennsylvania on November 3, 2020.^[1] The office of the Pennsylvania Secretary of the Commonwealth oversees the election process, including voting and vote counting.^[2]

To vote by mail, registered Pennsylvania voters had to request a ballot by October 27, 2020.^[3] As of early October some 2,568,084 voters requested mail ballots.^[4]

On October 29, 2019, the Pennsylvania House of Representatives passed Act 77 by a vote of 138–61.^[5] Later that day, the Pennsylvania State Senate passed Act 77 by a vote of 35–14.^[6] Governor Tom Wolf signed Act 77 into law two days later.^[7] The law enacted numerous changes to Pennsylvania's election code. Voters were allowed to request a mail-in ballot without providing a reason.^[7] A person could register to vote up to 15 days before an election and vote in that election, instead of the previous 30-day period.^[7] It said that mail-in ballots and absentee ballots would be valid if received by 8 p.m. on election day.^[7] The law eliminated the option of pushing one button to vote for all candidates of the same party, called straight-ticket voting; instead, a voter would need to select each candidate in order to vote the same way.^[7] The law said the state would cover up to 60 percent of the cost for counties to replace their voting machines with systems that had voter-verifiable paper.^[7] Governor Wolf described the changes as the "most significant improvement to Pennsylvania’s elections in more than 80 years".^[8]

In response to the COVID-19 pandemic, the Pennsylvania House of Representatives and the Pennsylvania State Senate both unanimously passed Act 12 on March 25, 2020,^[9][10] and Gov. Wolf signed it into law two days later.^[11] Act 12 delayed the primary election from April 28 to June 2. Act 12 also allowed counties to begin counting ballots at 7 a.m. on election day rather than being required to wait until 8 p.m. to do so.^[12]

There were no statewide ballot measures up for election in this general election; however, there were local ballot measures in Pittsburgh and Philadelphia.^[18]
