Answer:
Explanation:
''Most of the state and local level public officials in the U.S. are elected directly or indirectly. An election is the process by which people choose their representatives for governance. In the U.S., each state controls and regulates state and local elections. State law and state constitutions regulate elections at the state and local level. The state legislature controls state laws and state constitutions. Every state is free to conduct its elections and limit its electorate. State legislatures and the executive are elected separately. In all states, the governor and lieutenant governor are elected. Additionally, all members of the state legislatures are elected. The legislative branches in local level, county, and city government are filled by election. Sheriffs and Mayors at the local level are also elected''
