Majority of this forum is a joke.
While Florida is one of the states they performed better in (compared to other polls at least), let's break this down:
2018 Gov: R+3 (50-47), final result was similarly a tie (49.6-49.2) for the sake of simplicity lets round it and say the R vote was spot on, they underpolled D's by two, that would make this a 48-48 tie.
2018 Senate: R+2 (49-47), final result was statistically 50-50 (0.11% margin) so they underpolled R's by 1, D's by 3. That would make this a 49-49 tie.
2016 Pres: R+4 (50-46), final result was 48.6-47.4, about a one point lead. Again, R's were overpolled (this time by about two points) and D's underpolled by one, which were that error to occur would give us D 47-46.
Further showing Florida is a pure tossup rather than a Trump trend.
