Pennsylvania officials have BUSTED a large-scale fraudulent voter registration scheme

Can someone explain to me how and why they get away with all this?

Lancaster, Pennsylvania officials have BUSTED a large-scale fraudulent voter registration scheme that includes thousands of applications with the same handwriting, fake signatures, false addresses, etc

They discovered the same scheme in other Pennsylvania counties.

District Attorney Heather Adams revealed that the applications came from canvassers who were paid to obtain voter registrations, adding that "The majority of the applications were from residents in the city of Lancaster... The canvases themselves took place at various shopping centers, parking lots of grocery stores and businesses, sidewalks and parks."

"We are aware of at least two other counties that receive similar applications that are currently being investigated."

If you listen closely, the DA said the Clerk received the applications at or near the deadline to register to vote. That means the bad actors waited till the last minute so no one would notice. They would've used the fraudulent applications to commit mail-in ballot fraud without getting caught.
