The Pennsylvania Supreme Court has ruled that voters whose mail-in ballots are rejected for defects must be allowed to cast provisional votes. This decision emphasizes that provisional ballots should be counted if the traditional mail-in ballots are disqualified, providing voters a second chance during crucial elections. The ruling is particularly significant in Pennsylvania, a key battleground state, as it ensures that voters who may have made errors on their mail ballots will have the opportunity to participate in the election process.
