I presume they still “count” the signatures, by verifying that each page is filled in, or looking at the number on the last signature, and adding them up.
They simply don’t go back and get the names and addresses and check them against address lists and voter registrations.
I didn’t think you needed to be registered though, just old enough to vote.
“But those 11,050 are going to be matched against the the registered voter rolls and many are likely to be thrown out.”
