In Florida the party submits a list of candidates to appear on the Presidential Preference Primary.
It is unclear how the Republican party decides the list.
It may take some good ol' Republican grassroots support and determination.
Florida's closed primary will be held on March 17, 2020.
A closed primary means you must be registered to vote as "affiliated" Republican.
The deadline to register to vote or update your 'party affiliation' for the Primary is February 18, 2020
