    Governor Bush remained true to his conservative principles throughout his two terms in office – cutting nearly $20 billion in taxes, vetoing more than $2.3 billion in earmarks and reducing the state government workforce. His limited government approach helped unleash one of the most robust and dynamic economies in the nation, creating 1.3 million net new jobs and improving the state’s credit ratings, including achieving the first ever triple-A bond rating for Florida.

    During his two terms, Governor Bush championed major reform of government, in areas ranging from health care and environmental protection to civil service and tax reform. His top priority was the overhaul of the state’s failing education system. Under Governor Bush’s leadership, Florida established a bold accountability system in public schools and created the most ambitious school choice programs in the nation. Governor Bush is also known for his leadership during two unprecedented back-to-back hurricane seasons, which brought eight hurricanes and four tropical storms to the state of Florida in less than two years. He worked tirelessly to improve the state’s ability to respond quickly and compassionately during emergencies, while also instilling a ‘culture of preparedness’ in the state’s citizenry.

    Governor Bush previously served as a Presidential Professor of Practice at University of Pennsylvania. He also served as a visiting professor and fellow at Harvard University, an executive professor at Texas A&M University, and has been awarded several honorary doctorates from collegiate institutions across the country.
