No, she’s not running. Thats not the point!
So what is the point?
As much as many of us believed in a Palin candidacy, hindsight makes it fairly obvious she never was seriously considering a run. She didn't wish to pursue the office and chose instead to keep her current life for whatever the reason. While I think the timing of her announcement and the way she did it was far from great, I'm still grateful for the role she played in the 2010 elections.
I think she likes the speeches and her (now lessening) ability to influence the argument, but the reality is she made herself “a ship in the harbor”. In terms of endorsing or promoting a specific candidate, I haven't seen it and don't anticipate her to in the immediate future.
