Actually, the Anchorage Times said something similar just after she was nominated (before the Obama team got to them). They said something to the effect that every time she met with their editorial board, she came alone. She didn’t bring handlers, advisors, or PR people. She was the only high-ranking government person to do that in their memory.
Pretty classy.
She has much in common with Ronald Reagan. Both working without notes, And forming their opinions on their own competent analysis of the facts.
Probably two of the five greatest intellects to participate in American government. (the other three being Jefferson, Madison, and Franklin)
