Probably Greeley at the time.
So you're pro-Klan?
His inclusion of "at the time" leads me to think his South Carolina residency is factored in as well. Not that such changes much, but, y'know.
Give his '#Ready4Strom' username, I figure he'd be a traitor rightfully denied the right to vote.
Reconstruction was going particularly bad in South Carolina and their corrupt (the Redeemers exaggerated while minimizing their own, but there was definitely major corruption rampant in the Republican regimes) government was held up by Grant, I would suggest you actually take a look at the gang of people who were running the state during Reconstruction (of course Hampton and his people were little better, but that's life in postbellum SC). It was so corrupt and mismanaged that even some blacks cast in their lot with Hampton in 1876.
