You should have recently received a new voter registration card from the Supervisor of Elections Office. I assumed they were just sending out new ones because of the elections coming up- not realizing the boundaries of precincts have changed and as a result, polling locations have changed for some in District 5.
Almost every precinct in District 5 saw its boundary with an adjacent precinct shift a few blocks. This is all due to the Congressional District boundary changes between the seats currently held by Corrine Brown and Ander Crenshaw. You will recall that the boundaries of CD4 and CD5 were in dispute and subject to court challenges. Ultimately, the boundaries of CD5 (Congresswoman Brown’s current District) which extends into City Council District 5, changed and as a result you see these precinct changes. The boundaries of City Council District 5 do not change- but the Congressional District that appears on your ballot may be different than last election.
