William Alexander McCain had owned 52 slaves. The senator seemed surprised after Salon reporters showed him documents gathered from Carroll County Courthouse, the Carrollton Merrill Museum, the Mississippi State Archives and the Greenwood, Miss., Public Library.
"I didn't know that," McCain said in measured tones wearing a stoic expression during a midday interview, as he looked at the documents before Tuesday night's debate. "I knew they had sharecroppers. I did not know that."
...
"I knew we fought in the Civil War," McCain went on. "But no, I had no idea. I guess thinking about it, I guess when you really think about it logically, it shouldn't be a surprise. They had a plantation and they fought in the Civil War so I guess that it makes sense."
"It's very impactful," he said of learning the news. "When you think about it, they owned a plantation, why didn't I think about that before? Obviously, I'm going to have to do a little more research."
Then he began to piece together information out loud. "So maybe their sharecroppers that were on the plantation were descendants of those slaves," he said.
