Hardly a great resource. "American Caeser" is no more an unbiased account of Abraham Lincoln and his record than Carl Sandburg's books are.
That’s like saying “Lincoln’s own words are no more an unbiased account of Abraham Lincoln and his record” since half the book is original text - COMPLETE original texts and not just quotes for simple-minded people to claim are distortions and taken out of context.
But thanks for the two cents. I always appreciate feedback from people who haven’t read for themselves.
