Wrong.
The Democratic Party wasn’t founded until 1828, well after the establishment of slavery.
It wasn’t until the 1850s that slavery would become an issue.
And that's a defense of the Democrat party? You didn't support slavery until 1828?
And bull to your bull slavery wasn't an issue until the 1850s, it was a huge issue in the founding of the country and before. Have you heard of Penn and the Quakers?
