Registration facilities are made available to the residents of Florida by the Supervisors of Elections by keeping courthouse offices open eight hours a day. five days a week. and for several weeks prior to each election the office is open six days a week and from eight to twelve hours a day. Temporary offices are established in various municipalities of the counties. at colleges and other areas. Mobile units are also used at shopping centers. places of industry. migrant housing projects and many other areas. Florida also allows registration by mail to: (a) Members of the armed forces while in active service and their spouses and dependents. (b) Members of the merchant marine of the United States and their spouses and dependents. (c) Citizens of the United States who are permanent residents of Florida and are temporarily residing outside the territorial limits of the United States and the District of Columbia. and their spouses and dependents. (d) Citizens of United States who are permanent residents of the state and are temporarily outside the state. and (e) Residents of the state who are physically and unable to register in person. We are of the opinion that any voter who is a resident of Florida and having a desire to register certainly has the opportunity to do so.
