However, if a resident must vote Tuesday, election officials encouraged people to go to their pre-assigned polling place to speed up the process.

“If you can’t get to your own polling location, you can go to any polling location in the county and vote a provisional ballot,” said L.A. County Registrar, Dean Logan.
