This really illustrates how undemocratic the Electoral College is; in this scenario in which every anti-Lincoln vote is cast for the same candidate, Lincoln loses the popular vote by more than 60% to 40% but still wins.
No, it just demonstrates how undemocratic the South was. I'm sure the popular vote would've been much closer if 1. Lincoln had actually been allowed on the ballot in the South and most of all 2. they hadn't been actively disenfranchising the overwhelming majority of their population
