Especially good is if it is under +5 for Trump. That's right around where Marist and YouGov have been placing it, who are two of the higher quality pollsters who have been operating in the area.
Especially bad is if it is more than +10 or so for Trump. That is more line with NYT and some of the so-called "red-wave" pollsters and does not bode well.
Again, not lethal—there's a lot of nonlinear effects in play that are unique to Florida—but that's what I'm watching there.
