It looks to me like Sarah Palin is laying the rhetorical ground work for a Presidential run
She is learning how to speak in sound bites, staking out positions on issues, keeping her name in the press and improving her overall image.
Will it work?
Who knows?
Sarah can be on the political stage without being held back...and she brings an audience with her.... who most politicians would love her to endorse them for that audience....and that's what she does and is par-excellant at doing.
