Could be Sarah wanted to get in good with the establishment Republicans should she herself choose to run for office later.
We had that happen with the Rockefeller Wing when Barry Goldwater was nominated. They walked away. We don't even have any Republicans like them anymore ~ sure, some RINOs, but not the Rockefeller type. People remembered and made sure to cut them deep if they tried surfacing. That helped get us Ronald Reagan.
Walking away is a kiss of death ~ to be avoided if possible.
What we need is for McCain to STEP ASIDE NOW to give someone other than JD a shot.
...and risk lopping off a sizable chunk of her base in the process. Wise move? Me thinks not! For me I'm now viewing Palin through a lens of wary suspicion.
