http://www.nma.tv A string of disparaging Twitter messages sent from a Sarah Palin staffer have been obtained by The Daily Caller. Advisor Rebecca Mansour vented about several high profile individuals. She alleged Mitt Romney's "lackeys" were trying to back stab Palin. In another rant, Mansour suggested they "go medieval" on author Joe McGinnis after he moved in next door to Palin to research a book. She even turned on the Palins themselves, likening Bristol to past political family embarrassments. But Sarah Palin needn't worry about bad publicity. A two-hour documentary is coming out this Fall championing her tenure as Alaskan Governor. ADD LI ANNE ON FB: http://www.facebook.com/nma.lianne
