Part of the war against Palin was to portray her as divisive.
When a governor proves to be perhaps the most popular governor in history, with numbers commonly in the 80s, the high 80s and even 93%, then they are a uniter, a person who is reaching all the people, of all persuasions and parties, there is just no way to describe someone who everyone approves of, as divisive.
Romney lost an election that couldn’t be lost in 2012 and what was his political history? A single governor’s term where he was run out of office with a 34% approval rating.
She was divisive. Not among the base, which she united like McVain alone never could. But the reaction within the MSM and among libs generally showed her to be as maddening to them as a Reagan or a Goldwater. That she divided Establishment and conservative Pubs, as well, demonstrates where lies the Establishment on the spectrum.
