The clock is ticking toward the deadline to register to vote in Florida's presidential preference primary next month. You have until tomorrow to register, change your address or party affiliation to vote in Florida's presidential primary next month. Because Florida has a closed primary, you can only vote for candidates of the same party you are registered with during the primary. Broward Supervisor of Elections Peter Antonacci says there are 335-thousand "NPA" voters in Broward who will not be able to participate during the Primary March 17th. Early voting begins March 2nd.
