Costa's campaign website listed the following issues:
- Excerpt: "I oppose Obamacare. Health care decisions must be left in the hands of patients and physicians, not the government. As the wife of a physician and with 15 years in the medical profession myself, I recognize firsthand that health care reforms are needed."
- Excerpt: "Using the same “back to basics” approach I used as a Mayor, I believe we must stop government intrusion into the private business sector, cut job-killing taxes and wasteful government spending, allowing Americans to receive the rewards of their hard work."
- Excerpt: "The current tax structure is out of control. We need a tax system that is simple and equitable such as the Fair Tax or Flat Tax proposals, or any other viable option that would be equitable for all Americans."
- Excerpt: "We must have local control of our educational system, whether it is public, private or home schooling."
- Excerpt: "The Federal government has the constitutional obligation to provide for the common defense of our nation. It is imperative that our foreign policy is clear and concise. We must never underestimate those who seek to do us harm and we must make it crystal clear we will act swiftly and decisively when necessary."
Costa and her husband, Dennis, have nine children.
