Lincoln fucking broke our country and caused the civil war. Greatest president my ass, Lincoln was the literal worst. While I agree that slavery is morally wrong and support outlawing it, the dude pushed the issue too hard and didn't even try to phase it out or work on building Southern economies to move away from slave labor.  Further, southern states tried to secede peacefully and he made it all about the federal armories and how they should give it all back? Sure, let's just give any weapons we could use to defend ourselves! Nevermind the fact that Southern taxes helped pay for it in the damn first place. Whether we agree with him or not, Lincoln was the only president to break our nation. That automatically puts him at the bottom of the list.
