Eh...a 4% swing to Biden is OK, I guess, but pretty weak compared to the swings we’ve seen in other district polls, which are very often double digits.
IIRC, Pasco is a very Trumpy place. Not hard to imagine that Biden barely makes any headway here.
Exurban areas like Pasco are the core of Trumpism in FL, not the rural areas.
Because of the legacy of segregation, most of the WWC neighborhoods in the sunbelt are mostly exurban areas. They can't afford to live in places like Alpharetta and East Cobb and don't want to live in minority heavy neighborhoods like Norcross and Riverdale.
