In California, Republican bastions under threat from 'blue wave'

As the door slammed in his face, Josef Siroky understood that campaigning for a Democrat in the conservative California city of Huntington Beach was not going to be easy. Siroky is one of hundreds of volunteers canvassing the Golden State's conservative bastions like Huntington Beach, which Democrats are hoping to conquer in the November 6 midterm elections en route to winning control of the House of Representatives -- and possibly, Congress. On a sunny Sunday in October, Siroky and the other volunteers are going door-to-door for Harley Rouda, a former Republican who is now running for office as a moderate Democrat in a tight race with a veteran Republican.
