According to this author Abraham Lincoln was a cronic depressive to the point of virtual psychosis and to the point of being suicidal. He seems to think that if Lincoln was living in present times he would have likely to have been institutionalized for at least some amount of time and he could never have been elected president. This is not, however, a critical biography. The author does appear to consider Lincoln to have been a great man and a great president. In fact, he seems to think that Lincoln could not have reached his greatness without his bouts with severe depression.
