I believe Governor Palin has come to see her role as a outsider, not personally connected to any specific politician.
By maintaining her independence, she maintains her freedom to express herself without filters. Considering how much the inside-the-beltway power structure can influence federal government, her strong common-sense advocacy can be a great public service.
For evidence, look at the current Presidential campaign. As I said in another post, Donald Trump is Sarah Palin’s payback to the Republican Establishment.
Evidently, Momma Grizzlies memories are longer than elephants.
I’d love for DJT to appoint her to the EPA with the sole task to shut it down. Then onward to the DOE, and on and on until the Feds were in 100% compliance with the Constitution. She would take no prisoners ~ ha!
