Texas has a plural executive system with independently elected executive branch officials, unlike the cabinet system used by the federal government and most other states. This reflects Texas' conservative tradition of limiting any single official's power. Elected positions include the governor, lieutenant governor, attorney general, comptroller, land commissioner, agriculture commissioner, and appointed positions like secretary of state. Various boards and commissions also operate independently to regulate industries and oversee agencies, universities, and occupational licensing. The extensive bureaucracy carries out laws under the direction of these numerous elected and appointed officials.
