The Pennsylvania line-by-line petition-checking process for the statewide Libertarian Party petition has been proceeding this week, just as it has for each of the two previous weeks. On September 26, enough signtures had been validated by the adversarial process so that the petition now has the needed 20,601 valid signatures. Furthermore, there are still some signatures to go through the process.
It appears that the only possible method for the statewide candidates to be removed from the ballot now would be a ruling from the Pennsylvania Supreme Court, reversing the Commonwealth Court on whether certain signatures are invalid. The Commonwealth Court had ruled that signatures of voters are valid if that signer moved since re-registering and signed with the new address, whereas the old address is still on the voter registration rolls. This ruling only pertains to voters who move within the county, not voters who move to another county. Assuming the Pennsylvania Supreme Court approves this ruling, or takes no action, then the statewide Libertarians are on the ballot.
The only other parties on the ballot for statewide offices are Democratic, Republican, and Green, and the Green Party petition only listed a presidential and vice-presidential nominee; there are no Greens running for U.S. Senate or the other statewide offices. By contrast, the Libertarian petition nominated candidates for U.S. Senate, Attorney General, and Treasurer.
