The pushback concerning Newsweek's decision to publish a cover story asking "Why Are Obama's Critics So Dumb?" continues.

On Tuesday, former Alaska governor Sarah Palin weighed in on Twitter saying, "@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":

As NewsBusters has reported in the past, Newsweek's Andrew Sullivan is amongst the absurd media members advancing the conspiracy theory that Trig Palin isn't Sarah's son.

Now he's on the cover of this shameless liberal rag.

If you were Palin, would you be angry, too?
