Sarah Palin has informed her supporters she’s not running for president in 2012.
I have long thought, and continue to think, she sees her role as an influencer, not as a leader. She originally had eyes on the White House, but, between the current political tempo of the USA, the fact that she is a woman in a nation not willing to elect a woman (just look at Hillary Clinton vs Barack Obama), and her litany of amazing gaffs -- she realized she is better at stirring things up than as a potential president.
Please understand my own position is not as a supporter, nor detractor. I'm not a Republican for a myriad of good reasons, and certainly not a Democrat for a similarly wide array of reasons.
