Sarah Palin has made about 30 endorsements in GOP primaries this year but her batting average is starting to flatten out. So far, she's picked 12 winners (like Nikki Haley in the South Carolina governor's race) and eight losers (like Karen Handel, who conceded a squeaker in the Georgia governor's race on Aug. 11). Her feel for statewide races is good, but she has struggled to pick winners in House contests. Her O.K. can surprise even the candidates: she backed long shot Marylander Brian Murphy over former governor Bob Ehrlich in the runoff for the governor's seat by announcing it on her Facebook page.
