Bob McDonnell backed Romney early and could help deliver his Virginia home state to the Republicans after they lost it to Obama in 2008. McDonnell would face questions about a law he pushed through the state legislature requiring women to have an ultrasound procedure before having an abortion. Romney opposes abortion but may want to avoid anything that could distract from his central economic message. Republicans are having enough trouble appealing to women voters as it is, which is why McDonnell is unlikely to be the choice.
