Any presidents who were treatrd. Unfairly at all

I think most of the presidents immediately leading up to the Civil War, i.e. Pierce, Buchanan, etc. are treated unfairly by history. There really wasn't much they could do to ease the tensions between the abolitionists and the pro-slave members of Congress, and at the time the executive was relatively weak compared to Lincoln and some of his successors. Besides that, if you read up about Pierce, he had to have had one of the most tragic lives of any American President. All three of his children died during childhood, one of them because of a train accident (he was crushed to death and nearly decapitated). I don't see how anyone could govern effectively with all that tragedy.
