With help from left-wing organizations, the largest urban cities and counties in the battleground state of Pennsylvania are going all-out to help thousands of voters replace flawed ballots submitted via mail. 

Pennsylvania law requires that voters "shall...fill out, date and sign the declaration" printed on the ballot's outer envelope. Republicans have been litigating to ensure that election officials follow the law and invalidate ballots with improperly prepared envelopes. 

Depending on where you live, it seems any date will do just fine. "There has been evidence that at least some Pennsylvania counties have deemed any date to be acceptable, even dates in the future," according to the Associated Press.
