One poll (which ended on October 2) finding surprisingly good numbers for Democrats certainly doesn’t invalidate two other more recent ones, lol. And Nelson underperforming Gillum by 5 is definitely not good news for him in any way.
It’s not Nelson underperforming Gillum as much as Scott outperforming DeSantis. Nelson and Gillum are both at 48. DeSantis is just largely unknown compared to Scott.
Scott has been a good Governor for the last 8 years. He was elected under the Tea Party Label in 2010 but since then pivoted to the middle especially the last 4 years after beating Crist. The only Poll post "Michael" from St. Pete shows 62% of Voters approving of the Governors Response to the Hurricane. If other Polls in the coming Days bear that out Scott will be in the Drivers Seat soon particularly after Nelson got back on the Campaign Trail.
And this same poll post-Hurricane Michael also shows that Scott is ahead by 12 points among Hispanic voters, one of the key voting groups for a victory in Florida.
