As you know, and you well know this, in person voter fraud is an enormous issue with more than - exactly 10 documented cases of it in the entire country alone! Just since the beginning of the millennium. That's .000000284% of all votes. So you can see why Pennsylvania would want to enact a voter ID law which one study claims could potentially disenfranchise over 758,000 registered voters, or around 9% of the entire Pennsylvania electorate. But that's the price you pay to prevent something that doesn't happen.
