The number of Florida Republicans is up by more than 6 percent compared to the last presidential preference primary four years ago.
Voter registration numbers released Tuesday show that the biggest gains in GOP voters occurred in counties where Republican presidential candidate Mitt Romney did well in 2008.
An Associated Press analysis shows that more than two-thirds of the gains in registered Republicans were in Florida counties where Romney finished in either first or second place in the 2008 primary.
Romney lost in the Florida primary to eventual nominee John McCain in a field of nine candidates.
The biggest gains in registered Republicans since 2008 have been in Lee, Broward, Orange, Hillsborough and Escambia counties.
Florida Republicans are set to pick their presidential candidate on Jan. 31.
