It was an awkward moment, topping even Barack Obama's meeting with the president he spent two years running against: Economist and Times columnist Paul Krugman, receiving congratulations for his Nobel Prize from the man he said built the "Party of Stupid," who "got rid of accountability," and who "was lying" about his "patently, shamelessly dishonest" budget, among many, many other brutal criticisms Krugman has leveled against the president over the past seven years. The photo, by Chip Somodevilla, says plenty, but hopefully Krugman will write something (for his blog?) on the words that actually came out of the president's mouth at the Oval Office meeting.
