// Why would any sane person not register as an independent? You can still vote in the primaries of your choice, and you’re not “tagged” for political pestering. //
It depends on if you are in a closed or an open primary state. FL is a CLOSED primary state.
I understand.
In my state (alas, MA, where my vote is counted but doesn't count), it's more of a hybrid. If you are enrolled for a party, you can only vote in that party's primary. If you are unenrolled (i.e., independent), you can choose which primary ballot you want at the polls on primary day.
