I see what the history books report, it calls Breckenridge a Southern Democrat and Douglas as a pro-slavery Democrat, Bell was a middle road, not take a stand on the issue. Lincoln was anti-slavery.
Take it or leave it because you have failed to make any points. Beckenridge was listed as a Democrat and then a Southern Democrat. In 1956 Buchanan won all the southern states.
You have yet to disprove either statement, though you claim they aren't true.
I hate to break this to ya but Buchanan won no states at all in 1956. He was dead. And a hundred years before, as already repeatedly noted, he was effectively the only candidate in the South. Your option to show us how Millard Fillmore was a viable competitor is still on the table. Untouched.
And then there's 1860 and the mysterious uppercase letter you put in your own posts without getting the significance thereof. I need a history lesson from no one on this, thanks. You can't even comprehend the idea of a separate political party. Go look up the US political parties of the 19th century if you actually think that a political party has to last a century, or whatever it is you think in this utterly irrational tangent of yours.
Just for the sake of clarification, Douglas was wishy-washy on slavery;
that's exactly why the Southerners who walked out and struck out on their own rejected him. After being defeated he worked with Lincoln to try to preserve the Union for the brief period he was alive. Bell was from a Whig/Know Nothing base, the former of which was also wishy-washy (that's why that party disintegrated) and the latter of which chose to ignore the question hoping it would go away. Breckinridge and Lincoln were of course unequivocal, representing opposite sides but at least taking a position. Actually Lincoln made some contradictory statements on the issue but his new political party had a position.
None of this is relevant to the fact of separate political candidates from separate parties, but it does demonstrate the superficiality of your homework. You get an "E", and that doesn't mean excellent.
