Good decision by Caroline Kennedy. It's purely speculation but here's one hypothesis around why: she's been widely and justly admired as a pillar of strength throughout her life - while losing her entire family in tragic and public circumstances. She's been an understated, consistent and (as liberals go and until the dawn of the Obama era) has been relatively moderate presence - most notably in supporting the JFK Library. She appears to have a strong and admirable family and personal life.Hub Blog tried to convey a similar sentiment when she first expressed interest in the Senate seat.
And now - welcome to the political slimepit, Caroline. Suddenly - abuse from all quarters. All of us should ask ourselves: who really needs it?
I suspect over time, respect for her will return and grow. If this hypothesis is right, she really is different from the vast majority of politicians.
