Why the Snub?

Jon Swift, with his usual brilliance, wonders why Obama didn't take any questions from FOX News during his first press conference:

Apparently, Obama still holds a grudge against the network, and its president Roger Ailes, for reporting that he went to a madrassa as a child, joking about assassinating him, referring to him as a socialist, attacking him for calling his grandmother a “typical white person,” calling his cigarette smoking "a dirty little secret" and asking its viewers “Would you vote for a smoker?,” mixing him up with black former congressman Harold Ford Jr., making a joke that his name was similar to Osama Bin Laden’s and who knows what other perceived slights. Unfortunately, the Fox reporter was prevented from asking such very important questions as which cabinet post William Ayers will be appointed to and which policies from the Communist Manifesto Obama was planning to implement first.
