Under Florida law, voters must be legal residents of the state and of the county where they register to vote. Guidelines from the Florida department of state say that Florida courts and state authorities have defined legal residency as the place “where a person mentally intends to make his or her permanent residence”.

Wilfully submitting false information on a Florida voter registration – or helping someone to do so – is a third-degree felony punishable by up to five years in prison.

Election officials in Miami-Dade make clear to prospective voters that they are required to actually live in the county and to use their home address in election paperwork. “You must reside in Miami-Dade County,” their website states. It adds: “When you register to vote, an actual residence address is required by law.” A county spokeswoman did not respond to questions relating to Bannon’s situation.

Three neighbors said the house where Bannon is currently registered to vote had been abandoned for three months. When the Guardian visited the property on Thursday a large window in the front aspect was missing. A soiled curtain was blowing through it. The driveway was a mess of tree branches and mud.
