The big problem with that is turn-of-the-century politics, and today’s Dems LOVE Lincoln and Yankees.
It’s the only time they love the “USA”. All other times they hate it.
Don’t fool yourself.
It’s the opposite for southern sympathizers - they love the USA at all times, except the Civil War. :)
I can't stand it when the godless left claims the moral high ground on slavery, especially when "scientific racism" was heating up at the time from the left's holy book: Darwin's On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, published in 1859 (the year before the Christian abolitionists won the presidential election in 1860).
The slavery vs abolition thing was very much an extension of the spiritual war that was playing out during the Second Great Awakening.
