Heads up, there is a background discussion to the economic news.  Professional economists have ideologies, too.  This is a good essay that points out the ways the different camps respond to data.  Short version:  The Obama recovery beats the Bush (II) recovery, but right wing economists have repeatedly adjusted their models when the data turn inconvenient... This is about a defense of policies they like.  As to motive, that's a much longer path to map, but it doesn't take a lot of imagination.
