“the very next year the Christians won the 1860 election in the U.S. (Lincoln)”
That claim would surely have amused Lincoln. Two of Lincoln’s closest friends, William Herndon and Ward Hill Lamon, insisted that Lincoln was a skeptic just like they were. Lincoln never professed the Christian faith and never belonged to a church. He could quote Scripture, but as William Shakespeare noted, so could the devil
The anti-slavery movement in America originated among Quakers who believed in peaceful means. The abolitionist movement of 1860 was violent and driven by Transcendentalists out of Boston.
My point is not on whether or not Lincoln himself was a hard core Christian believer that'd be the best person to lead a Sunday school class. IMHO his faith or lack thereof is a lot like Trump's. Trump wasn't popular among Christians for any great essay he wrote over the theological differences between Calvinism and Arminianism. Both Lincoln and Trump were popular among Christians because they promised to do like the Christians wanted (at least in Lincoln's case, up to the RNC in 1860).
