His experience as a politician was limited before he made it to the White House. According to one imperious professor from Harvard, 'Never did a President enter upon office with less means at his command.' A newspaper observed that he 'cannot speak good grammar'.
All of his rivals for the Republican nomination were far more accomplished and knowledgeable. He sought to compensate for his lack of expertise by appointing political veterans to his cabinet, but this only resulted in widespread perceptions of the president as a figurehead. Then with utter confidence, he led the nation into a major war that millions of Americans considered to be totally unnecessary and pointlessly destructive.
But enough about Abe Lincoln.
A great companion piece to a fact I have long treasured. The only US President in history with a degree in economics was ......... Ronald Reagan.
