Many conservatives are furious over Newsweek's controversy-bait cover story by Andrew Sullivan, whose headline asks, "Why Are Obama's Critics So Dumb?"
Sarah Palin is taking it particularly personally, though.
"Know what's truly 'dumb'?" Palin Tweeted. "Giving a cover story to the Trig Truther conspiracy kook writer who thinks I didn't give birth to my son."
In a play on the "Birther" conspiracy surrounding Obama's birth certificate, Palin is calling out Sullivan for questioning whether she is Trig's real mother.
In 2008, Sullivan and others theorized that a Sarah Palin pregnancy scandal involving a cover-up of Bristol Palin getting knocked up could be in effect.
Bristol was, of course, pregnant with Tripp, not Trig.
He hypothesized that Palin "faked the pregnancy to avoid embarrassment for her daughter [Bristol Palin] or for political gain or some combination of reasons."
Sullivan's response to Palin calling him out today?
