The Williamsport Sun-Gazette his this story about the Green, Libertarian, and Keystone Parties. All three are on the ballot for the statewide offices. The only statewide offices up this year in Pennsylvania are U.S. Senate, and Governor-Lieutenant Governor.
Polls this week are indicating Democrats are comfortably ahead in both statewide races. No one challenged any of the three minor party statewide petitions this year.
Pennsylvania law requires a party to have 15% of the statewide registration, in order to be truly ballot-qualified. No minor party has ever come close to meeting that standard, which has existed since 1986. However, if a minor party polls 2% of the winner’s vote for any statewide office, it is listed on voter registration forms, and is automatically on the ballot in special elections. Both the Libertarian Party and the Green Party have this status in Pennsylvania, because they met that vote test in 2020.
