Gov. Sarah Palin shocked and awed just about everybody around the Capitol on Wednesday when she announced she’s expecting her fifth child. The governor, who recently turned 44, told a handful of reporters as she was leaving work to expect a new member of the first family, then headed to a reception at the Baranof Hotel to feast on king crab. Palin said she’s already about seven months along, with the baby due to arrive in mid-May.
