Old-Fashioned Liberalism. Marginal Revolution quotes a Herb Gintis review of a Krugman book:

...1950's liberalism was based on southern white racism and solid support from the unions, neither of which exists any more. There is no future in pure redistributional policies in the USA for this reason. Indeed, if one looks at other social democratic countries, almost all are moving from corporate liberalism to embrace new options, such as Sarkozy in France (French socialists have the same pathetic political sense as American liberals, and will share the same fate). I am sorry that we can't do better than Krugman. There are very serious social problems to be addressed, but the poor, pathetic, liberals simply haven't a clue. Conservatives, on the other, are political sophisticated and hold clear visions of what they want. It is too bad that what they want does not include caring about the poor and the otherwise afflicted, or dealing with our natural environment. Politics in the USA is no longer Elephants and Donkeys; it is now conservative Pigs and liberal Bonobos. The pigs are smart but only care about what's in their trough. The Bonobos are polymorphous perverse and great lovers, but will be extinct in short order.
