What keeps anyone from going from place to place and voting multiple times? Inquiring minds want to know.
You must have an official ID to vote in Florida (drivers lic., or state issued id). They scan this information into the computer which then issues you a coded/numbered ballot, which is the one that your precinct would use on election day with the particular state rep and senate races for your district. It is all strictly controlled, which I applaud.
You must not be a Florida resident. This is a big no-no if you are registered "R".
Florida runs a tight election process. You WILL get caught and go to jail. You also need an ID which is scanned into the system.
