Lincoln was quite easily the worst. From removing civil liberties, throwing citizens in jail with no trial or charges, using human shields during war time, not prosecuting war crimes, et al. Needless to say J.W. Booth was the best thing to come along during his presidency. Unfortunately he became a player about 2 years to late.
Ahh, yes of course. If only Booth had acted a couple of years before, you would still have your own plantation and a bunch of slaves to serve you.
And of course you d'have Stark as your loyal foreman.
