I think it is important to watch where the NPA vote goes in Florida. If it breaks +20 to the democrats it's going to be a problem. If it's around +10 for the democrats then the republicans probably pull out a very close victory. Anything around 50/50 or + for the republicans means blowout for the republicans if current trends hold.
I've pulled the cross tabs from the most recent
FAU poll. It has Biden up +2. The cross tabs are a bit wonky because categories are not totaling like they should but whatever. I'm looking for their breakouts on independents to see if there is a breakout one way or another. Their cross tabs show independents breaking out as follows: 116 - Biden / 112 - Trump. From that we get a 51%D - 49%R trend for independents. This is not showing a major break towards the democrats. If that is true then their vote totals will be mostly a wash.
It's looking increasingly like this is a base turnout election. If the republicans maintain current trajectory then by close of polls on Sunday they should be within 50k votes of the democrats. Add in the small number of votes the democrats will pickup from NPA voters and your looking at a ~70k lead on election for the democrats. It will all come down to election day turnout. If the republicans blow the doors off on election day as expected then they will win this election even with a slight shift of independents to the democrats.
The cross tabs indicate that 80% will cast their votes early with 20% remaining on election day. It also indicates that the election day breakdown of voters will be 42%R / 29%D / 29%I. That would yield a +~247k republican margin on election day (I am assuming roughly 1.9 million votes cast in FL on election day). If you calculate the NPAs into the margins with their lean from above it reduces the republican margin to +~236k. I am skeptical of this election day breakdown based upon the apparent cannibalization of election day democrat voters already underway, but we'll see what happens. That would yield a +150k republican registered voter advantage overall for Florida.
