Its very easy to change party affiliation in FL.
Im sure quite a few Ds are really Rs who flipped in early 2020 IOT vote for Bernie in the D primary.
Among my buds are several former union guys now domiciled in FL and affiliated with D party who are for PotUS with the passion of a convert. They have no use for Biden, Harris, Perez, Gillum, etc.
