If the Florida electorate is 7 % more Republican than in 2016, when the Republicans won Florida both in the presidential level (by almost 2 percentage points) and in the senatorial level with Marco Rubio (by 8 percentage points), then it's actually good news for the Republicans because with an electorate that is almost 10 % more Republican in Florida it increases Rick Scott's chances of victory there.
