Palin hearts old news. (Associated Press)

For that omission, Palin made Sullivan pay, via Twitter:

@Newsweek: know what’s truly “dumb”? Giving a cover story to the TrigTruther conspiracy kook writer who thinks I didn’t give birth to my son

That outburst is a reference to Sullivan’s obsession with Palin’s account of the circumstances leading up to Trig’s birth. Of course, the Trig situation wasn’t central to Sullivan’s case against Obama’s dumb critics, or even peripheral. It’s an old story, one that bears no relevance to today’s affairs and that no one really cares about anymore. A forgotten tale. So why on earth would Palin herself drag it back into the dialogue? Any guesses out there?
