White supremacy was a universal view at the time and not just limited to the South. While the North outlawed slavery, blacks weren't exactly welcomed with open arms and often times sent back to the South. The Dred Scott decision ensured that slaves were still slaves even if they made it to the North. Face it, at the time, the entire US was a bunch of racist bastards; it wasn't just a Southern thing.
