My perspective is classical liberal. I caution the reader not to slip into thinking that classical liberalism characterizes the foils Krugman sets against himself, chiefly Republican politicos. By and large, they do not represent classical liberalism, first, because they are politicos, and secondly, because they are Republicans.
From a study of all Paul Krugman\’s NYT columns. The basic thesis is that his committment to social democratic ideals obscures the fact that many actual proposals and positions are to the detriment of the poor.
You could substitute Conservative for Republican there and it would make perfect sense in the UK context.
