Governor Palin can surely view the current state of the GOP primary with a large degree of satisfaction. All the major players were either tacitly or openly endorsed by her at some point and the shift to right wing populism is fundamental to the main direction of the campaign.
Donald Trump and Palin go back to 2008 where he endorsed her, over Hillary, in the election. Ted Cruz stated, with every justification " I would not be in the senate (and now of course in the campaign) if it were not for Sarah Palin."
Marco Rubio was endorsed by Palin (via the tea party) for his senate run, Nikki Haley would not have given the State of the Union address and got involved in the campaign (badly as it turned out) if she had not been, at an absolutely critical time, endorsed by Palin when running for the GOP nomination for Governor.
Palin has made no secret of her support for the concept of Trump's campaign.She has stated this numerous times, appeared with him in New York City and interviewed him on OANN Network.
Her current PAC campaign features a photograph of Senator Cruz front and center and clearly both candidates are acceptable to her.
Palin famously said "You don't need a title to make a difference" The fact that 21 of 23 of her endorsed candidates in the 2014 mid-terms were elected and that the top two candidates, both, like her not from the Establishment, are dominating the primaries and the discourse proves the "sage of Wasilla is absolutely correct.
At this point in time one of Governor Palin's candidate choices will be the Republican nominee and possibly the next president. Not bad for a former PTA member from a small town in Alaska. A tribute to the American dream , an American dreamer and person of tremendous moral courage and convictions.
Like Moses she may get to the mountain top but no further, but can take infinite satisfaction in knowing that one or other of her "Joshua's" will reach the promised land and will create a new country built on the ruins of a corrupted society.
