Recent Florida polling has 48% Biden, 48% Trump. Latinos leaning to Trump, older (white?) voters leaning more and more to Biden.
The polling was very likely before this last week's revelations:
Trump's disparaging comments of military members as losers and Bob Woodward's revelations that Trump has known all along that the virus is 5x as deadly as the flu and is easily transmissible by breathing in viral particles yet publicly said it was no worse than the flu and that mask wearing and social distancing were bad ideas.
