I happen to agree with the author of this piece that Wilson was one of our very worst presidents. My reasons are many and varied, from his foreign policy (not really neutral in WWI from the beginning) to his propaganda campaign during WWI, the 1919 Red Scare excesses against civil liberties, his championship of the income tax, the Federal reserve, and, of course, the extreme Southern bigotry of his views, although as one descended from Southerners I hardly take a pro-Radical Reconstruction view of the period.
Curiously, my dislike of Wilson was actually formed reading the major ostensibly favorable multivolume biography by Leuchtenberg. One of the best short takes on Wilson is a little known (today) book by Sigmund Freud and Thomas Bullit titled Thomas Woodrow Wilson, in which the father of psychoanaltic frummery describes the psyche of "Little Tommy Wilson". It really is a must read for conservatives.
A couple of notes on the article: Wilson did appoint William Jennings Bryan as secretary of state, but the two never got along: Wilson was a psuedo-aristocrat, former president of Princeton, and Bryan a populist, though by no means a stupid or uneducated man. I mentioned above that Wilson was not really neutral during WWI, conspiring essentially with Sir Edward Grey, the British Foreign Secretary, (through is emmissary, Col. House, who pretty much described the whole thing in his memoirs) to tilt American 'neutrality' against the Central Powers and towards the Brits. Bryan, an honest patriot even if a fundamentalist mountebank in many respects, was appalled and, in what I have elsewhere described as the one principled act of his entire life, resigned as secretary of state in 1915 over the matter.
Wilson was also heavily under the influence of his wife, who was practically running the government after his stroke. Wilson's insistance that the US Senate accept the League of Nations "as is" ensured its rejection and failure.
Moreover, Wilson's whole vision of the post WWI world, the Fourteen Points, and the entire performance of the American delegation at the Versailles Peace Conference in 1919, which resulted in the infamous Treaty of Versailles, has been heavily critiziced by diplomatic historians. The classic which everyone should read on this is Peacemaking 1919 by Sir Harold Nicholson, who was a member of the British delegation. Wilson's lack of preparation was astonishing, and was a major factor in the disaster that ensued. I don't know if the book is still read, but when I was a graduate student in European history, it was one of those books you had to know, rather like Fritz Fischer's Germany's Aims in the First World War (Griff nach der Weltmacht in German)
