Transcribing: allowed

Dittos are allowed.

Only a birth date or address is required. No -a0 if birth date is provided and no -b0 if address is provided. This means P.O. boxes are okay if a birth date is written. If both birth date and residence address are missing, then it's -ab0. Be aware that the voter file only has birth dates for 95% of voters, since the state stopped providing that data in newer files.

Printed name is not required if legal signature is unambiguously legible.

County is not required for a hard match. However, the county must match and the name be unique to that county for a soft match based on name uniqueness. County is not required at all for candidates.

Write-overs are not deficient.
