I am sure that TTV argued, though it is not reported, that date of birth is required as a cross-check to voter name in order to establish a crossover vote.
dob is a side issue.
Perhaps the more important issue is access to the originals, not copies.
Affidavits have been filed with the TTV federal lawsuit that swear witness to the alteration of poll books using sharpee markers and white-out on information not related to the voter’s private information; in other words post-election fraud.
Usage of white-out would not be discernible on ‘copies’.
