Pennsylvania's delayed primary election was held June 2, but final results will not be announced until mail-in votes are counted, after Gov. Tom Wolf extended the deadline for receipt of ballots by one week for six counties impacted by protests, including Philadelphia and Allegheny.

"This is an unprecedented time for Pennsylvania and our nation as we face a major public health crisis and civil unrest during an election," Wolf said in a statement. "Voting is the cornerstone of our democracy, and I want to ensure that voters can cast their ballot and that it is received in time."

The six counties included in the executive order are part of a disaster emergency declaration the governor signed May 30 in response to civil unrest to provide all necessary assistance to the municipalities.

While the vast majority of counties have been able to process their applications and mail their ballots, the volume of applications in the six counties caused by the COVID-19 crisis combined with the recent civil disturbance make it necessary to extend the deadline for the counties to receive completed civilian absentee and mail-in ballots. Curfews, travel restrictions and other unforeseen circumstances have made returning ballots more difficult in these counties. The extension will help to ensure that voters in those counties are not disenfranchised through no fault of their own.

Republican legislative leaders criticized Wolf for changing the rules "at the 11th hour."

"Even in an emergency, the General Assembly has an obligation to protect our citizens while defending our democracy," said the statement signed by House Speaker Mike Turzai, R-Allegheny, and Senate President Pro Tempore Joe Scarnati, R-Jefferson, who complained that lawmakers were not consulted before Wolf issued the extension.

In-person ballots were counted and announced June 2. With the flood of mail-in votes still being counted, The Associated Press called four races in which incumbent lawmakers lost.

Three were in Democratic legislative primaries in Philadelphia: author and community organizer Nikil Saval was ahead of Sen. Larry Farnese; educator and community organizer Regina Young was outpolling state Rep. Maria Donatucci; and early childhood education executive Amen Brown was leading state Rep. Roni Green.

The fourth legislator to lose their primary, according to the AP, was state Rep. Adam Ravenstahl, D-Allegheny, who was trailing Emily Kinkead, an attorney with the Grail Law Firm in Pittsburgh.

There was only one competitive primary among the statewide races: a six-way race in the Democratic primary for auditor general that the AP had not called by the morning of June 3. In that race, Pittsburgh City Controller Michael Lamb and Nina Ahmad, a molecular biologist and former Philadelphia deputy mayor, were the leading contenders at press time.

Former Vice President Joe Biden and President Donald Trump won the Democratic and Republican presidential preference votes, respectively.
