While looking up old YA literature on HathiTrust, I ran across this, which is the voter roll for the Bronx in 1903.
It is what it is at first glance really, a tedious enumeration of voters, addresses and parties, useful only for genealogy. And noting that the United States did once have parties like “Social Democrat” and “Socialist Labor” (and the occasional “Prohibition”).
Then you turn up:
I have no idea what Charles H. Douglas’s party registration is. There wasn’t, that I’m aware of, a “defective” party. If his registration was bad, wouldn’t they just reject it? Was this the 1903 version of “show ID at polling place”? Persons with mental limitations (“mental defectives”) were forbidden to vote, so I doubt it is that.
If anyone knows anything about this, please post a comment here.
