You didn't leave room for the prefix. I count 164 bits for the
contests alone plus the prefix. How many bits are the date,
precinct, ballot type, ballot ID, etc.? The ballot number is 14 bits
alone for a 4-digit decimal number! So we're probably up in the 200
+/- bit range, not counting encryption.
