Sometimes there is nothing like a 900-page biography. Most of the time though, nobody has time for such a thing. Especially with many modern biographers who refuse to take a stand that resembles judgement towards their subjects.
Remember the Arrested Development episode where George Michael says his teacher loves Saddam Hussein and Jason Bateman is like, “You mean, she’s interested in Saddam Hussein” and George Michael says, “Nope. She loves him.” This is how I am with Lincoln.
