“I have heard many times that there was not one Whig or Republican slave owner owned slaves at the time of the Civil War. Since I know how to use a search engine I found many sources to confirm that.”
When you get a better engine, search Benjamin Burton, Republican, Delaware. Slaveowner.
Who the eff said that republicans did not own slaves.
When YOU get a better search engine find whether Delaware was a SOUTHERN state or not.
Context man.
