Walter Russel Mead, who as a British observer often gives a refreshingly new look at America affairs, has written a piece "The "People United" Goes Down in Flames. He argues, convincingly, that the result in the Wisconsin recall election was not that the Republicans outspent the Democrats, but rather that the left no longer is able to convince the public of their positions. This follows from his earlier pieces about the new Blue social model -- the left is still enamored of old policies that once worked but are no longer valid in today's world, but the public is ready, he argues, to move on and find new solutions better suited to our new conditions.
It is a long and thoughtful article, and well worth reading.
