Obama's Freeze on FOX

The Washington Post is reporting the possible "freeze out" by Barack Obama of FOX News in response to the inaccurate Muslim/madrassa story regarding his upbringing. And in my opinion, good for him. No one should be beholden to these hacks passing themselves off as journalists.
Of course unnamed sources at FOX, being the self-important entity that it claims to be, say that this is equivalent to shooting himself in the foot.

"One source familiar with the dynamic between Fox and Obama, who asked not to be named, said Obama and his staff are in for a rude awakening if they think they can write off Fox News. If a candidate is serious about running for president, he or she is going to need a network like Fox to reach out to all those voters in the red and purple states, the source said."

Earth to FOX "source": Anyone watching FOX News in a red or "purple" state is most likely voting Republican regardless of what Obama does.

Wouldn't it be bliss if others followed suit and shut out FOX to the point that they would struggle in interviewing prospective candidates? It would never happen, but one can wonder what would happen to a news outlet if a majority of candidates refused interviews on their network.
