Here in Florida, registered Republican voters head to the polls Tuesday for the GOP presidential preference primary. Donald Trump has all but secured the nomination. With 190,859 registered Republicans in Brevard County, the closed primary state ensures only party-affiliated voters participate. Workers at the Supervisor of Elections Office have been gearing up, delivering equipment for a smooth voting process. Polls will be open from 7 a.m. to 7 p.m. on Tuesday. Tomorrow, voters must vote at their designated polling place, which is based on their residential address.
