She has two babies in the house. One "special needs". If she was a full-time governor, like that skank in Massachussettes awhile back, she'd be a "quitter". I'm not a Palinite in any way, but anyone who calls her a "quitter" is an anti-family statist who thinks political power is more important than being a Mom. Alas, the GOP is as full of those monsters as the Dems.
Given 20-20 hindsight, she not only made a logical decision, but the only logical decision.
