No, it's fine, do you have any Idea to what this is though?
I really don't, as far as I can tell it was just a more radical form of the Republican Party (of the time, not the modern). It might have not even been an actual political party, just a split in the Republican Party between radicals and moderates.
It's interesting as far as I've read, the Democrats said they would have started Civil War had John C. Fremont won. We could of had an American Civil War in 1856 instead of 1860/1. No Abe, No Jefferson Davis, maybe no Lee, maybe no Grant, new American Civil War just because of a 4 year difference.
I'm going to look into this now. This would make an amazing alternate history discussion, maybe even a timeline.
