Let's go back to the last time the margin of victory in Florida was 6.0+ points: 1988.
That election, HW Bush prevailed over Dukakis 60.87 - 38.51 (a margin of +22.36). Dukakis only won a single county (Gadsden) by around 350 votes out of 12,000.
That election, Florida voted a whole fourteen points to the right of the nation!
I predicted White Evangelicals would abandon Trump. That Prediction doesn't seem too far fetched now otherwise Trump wouldn't be down 11 in Florida because that means Biden is even leading in the Panhandle.
We're looking at a 1988 landslide Biden win November right now.
