The Atlantic features an analysis of the HillObama split in the Democratic party (link here; h/t Ben Domenech via email).
Certainly it wasn't the author's intent, but with one sentence fragment in the post's first paragraph, the writer inadvertently throws away the only leg on which the Democrats' lass warfare, poor-are-getting poorer, your life sucks, Michelle-Obama-things-are-getting-worse-every-day meme was standing:
the white working class - the core of Clinton's support in Pennsylvania and in the Democratic electorate writ large - is shrinking as a share of the U.S. population, while the mass upper middle class, a crucially important of Obama's base (and one that enjoys outsized cultural and political influence), is expanding at a rapid clip
Finally, some truth...it hurts, doesn't it -- especially when your whole rationale for running for office is based around class warfare, and reinforcing the admittedly untrue claim that quality of life in America is declining and the middle class are quickly becoming The Poor, due to the unapologetic greed of The Rich.
