A Pennsylvania state court ruled that Philadelphia and Allegheny Counties cannot discard mail-in votes due to incorrect envelope dates, emphasizing that such errors violate the state constitution's clause on free and equal elections. This decision impacts the battleground state in the upcoming presidential election between Kamala Harris and Donald Trump, marking a victory for voting rights advocates. Additionally, Cook County voters can now apply for mail ballots for the 2024 Presidential Election, with options for permanent mail-in voting. In a related ruling, a judge mandated that Washington County must notify voters of mail-in ballot errors and allow them to vote provisionally, further protecting voter rights.
