Alternatively, and I'd argue far more likely, it's a vote against an absolutist hardline stance of "Unconditional Surrender" and the crackdowns on civil liberties the Republicians are pushing. No Peace Without Reunion was still an incredibly popular position, and in reality that was the faction Little Mac trucked with. If he wins, I think Congress is far more likely to see a case of transformismo with the War Dems and Moderate Republicans co-operating to isolate the extremes on both sides and, from their commanding position of military strength, try to intice Richmond into voluntarily laying down arms and reintegrating into the Union. Make it clear that this is a limited time offer though; that steady gains will continue to be made and the terms on the table will only get worse the longer they drag things out
