"I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States." The congress legislates, the president as chief law enforcement officer implements. Obama has ignored his oath. If Romney is just more of the same--if he isn't prepared to stand up for our country, for you and me and our families--why should we stand up for him?
