Leonard here describes American “Progressives” of the late-19th and early-20th centuries. But this passage also perfectly describes, without changing a single word, American “Progressives” of the early 21st century. Fancying themselves to be ‘scientific,’ “Progressives” now as then, have a wholly unscientific understanding of politics and of the state. That understanding, because it is unscientific, is romantic in the worst way: it is dreamily, often stupidly, unrealistic.
Democrats fully embrace this type of politics, Republicans do sometimes. As such, Hillary sounds like the competent technocrat when discussing an issue. It gives her an air of credibility and people feel comforted.
But she suffers from the problem described in this post. Here. The bottom line is issues rarely get resolved in how she expects, then she, like other progressives, blames someone else.
