If you don't subscribe to this newsletter from historian Dr. Lindsay M. Chervinsky, I recommend you do. This essay on Abraham Lincoln is fabulous.
> He understood presidential power, and more importantly, he understood where that power ended. But he also knew what the war required of him to win. And he was willing to do it and hoped Congress would make it legal later or that history would forgive him. That takes extraordinary bravery and also maybe a bit of insanity.
