“That is incorrect. I saw this topic discussed a month or so ago, and it turns out there were quite a lot of Republicans who owned slaves.”
What percent is “quite a lot”? Just because Politifact can name a few Republicans that owned slaves doesn’t mean it was common. I don’t think anyone believes the number of Republican slave owners was over a couple of percent.
From the 0% you mentioned, one is an infinity more than zero.
I've given you two.
Yes, in larger terms, Republican slave owners were few, but not zero.
I don’t think anyone believes the number of Republican slave owners was over a couple of percent.
The numbers of Republican slave owners was likely very small. I think most were members of the Whig party that moved to the Republican party. The "Republican" party was after all founded to oppose slavery, so a "Republican" slave owner is a bit of a contradiction, isn't it? :)
