Gov. Palin, in disclosing that she has meaningful conflict within, has demonstrated that she is a rational thinking woman. After all, she has a family...career...ambition and more all which place demands on her. In being open to this discussion she has indicated that she is open to thought, but that she returns to her anchoring beliefs in response to her intellectual analysis.
As far as the impact of this on her political future, especially her 2012 options, this disclosure will allow the Right to Choice population to recognize her as a candidate who at least has thought through her stance under the stress related to her situation at the time. As a result there may be a slight shift from the Left for some center of the road voters.
