"Good Presidents don't ignore the constitution and cause the death of at least 600,000 people for a dubious concept."
Umm are you forgetting the dubious hand that Jeff Davis and the rest of the "Confederates" had in causing those 600K deaths?
Had Davis and Co. not illegally taken the southern states out of the union...the Civil War would NEVER have happened.
Ergo...Jeff Davis is just as if not MORE responsible for the death of 600K U.S. citizens than Lincoln EVER was.
Sorry, not illegal. But nice try.
