Who is responsible for registering voters in the state of Florida?

The responsibility for registering voters in Florida primarily lies with the county supervisors of elections. Each county has its own supervisor who oversees the voter registration process, ensuring that individuals can register to vote, maintain accurate voter rolls, and facilitate the overall election process within their jurisdiction. This decentralized approach allows for localized control and administration aligned with state laws and regulations.

The other options mentioned do not hold the direct responsibility for voter registration in the same way. While the state governor and the Secretary of State play significant roles in the broader electoral process and governance of elections, they do not handle the day-to-day functions of voter registration. The election committee typically focuses more on overseeing the conduct of elections rather than the registration aspect itself. Thus, the county supervisor of elections is the correct answer as they are the designated officials tasked specifically with registering voters at the local level.
