It's President Barack Obama versus Sarah Palin.
The war of words began when Palin openly criticized the President for putting unprecedented limits on the use of nuclear weapons.
"That's kind of like getting out there on a playground, a bunch of kids, getting ready to fight, and one of the kids saying, 'Go ahead, punch me in the face and I'm not going to retaliate. Go ahead and do what you want to with me.' No, it's unacceptable," Palin said.
On Good Morning America, President Obama dismissed Palin's comments.
"...Last I checked, Sarah Palin's not much of an expert on nuclear issues," the President said. "If the Secretary of Defense and the Chairman of the Joint Chiefs of Staff are comfortable with it, I'm probably going to take my advice from them and not from Sarah Palin."
Meanwhile, Palin kept slinging it at the Southern Republican Leadership Conference in New Orleans.
"Now the President, with all the vast nuclear experience that he acquired as a community organizer and as a part-time Senator and as a fulltime candidate, all that experience, still no accomplishment to date with North Korea and Iran," Palin said sarcastically.
The politician once again used her hand as a crib sheet.
