They supported the war but thought that Lincoln was mismanaging it.
And opposed the excesses of Sherman et al.
Well, who wouldn't be opposed to George "burn 'em all" Sherman?
Shermans win wars. He's a type of general that is necessary - like Curtis LeMay in WWII and the cold war. Doesn't make a popular politician after retirement though.
I don't know if they're really that necessary. Curtis LeMay was Wallace's insane running mate in 1968, wasn't he?
Yes! I would have voted for him anytime, but of course most people would not.
