"What explains Mr. Obama’s consistent snubbing of those who made him what he is?"

"Does he fear that his enemies would use any support for progressive people or ideas as an excuse to denounce him as a left-wing extremist? Well, as you may have noticed, they don’t need such excuses: He’s been portrayed as a socialist because he enacted Mitt Romney’s health-care plan, as a virulent foe of business because he’s been known to mention that corporations sometimes behave badly."

Krugman, who worries that Obama is "still wrapped up in his dream of transcending partisanship."
