One possibility is she isn’t good at commentary. Seems she doesn’t add much insight when I hear her. Remember it took Reagan decades to perfect his communication skills.
This blurry commentary coming from Sarah is because she has been left out of the political loop, marginalized entirely.
This permanent political predicament she’s in leaves her unable to break any news ground. She’s left with giving rather pedestrian commentary that anyone politically engaged could offer, for much less than a million.
