Well, that would obviously lead to a lawsuit. Let's see where that goes. Would the existing justices refuse to swear the new ones in until after it was resolved?
That would be interesting. It would only leave 4 justices to hear the case, all of whom would be Republicans. Not entirely convinced that bodes well for it.
Also, if Dems can finally pick up FL-GOV next year, none of this will matter for redistricting anyway.
afaik it would for legislative districts, whose maps cannot be vetoed. The best option would be for Democrats to get independent commission initiative(s) on the ballot for 2020. At that point, FL would have a pretty sound redistricting process, assuming the commission setup is well-designed.
I believe part of the Democrat's strategy for next redistricting is to use ballot initiatives where possible to level the playing field. If the worst case scenario happens in FL
(GOP gov & all GOP Supreme Court), I could see Democrats pushing a commission initiative here. They would be foolish not to.
