No, he lost because populous counties like Polk, Pasco, Hernando, Volusia, Manatee and Sarasota all swung hard against him. His failure to recognize the threat that Scott posed and bury him early is what sunk him more than a poorly-designed ballot.
I mean, obviously there are various larger factors of underperformance for the race to even have been close at all after Nelson won by a whopping 13 in 2012.
He absolutely dropped the ball, no question. The question being asked is, would this minor technicality have been enough to tip the outcome from very, very narrowly Scott to very, very narrowly Nelson? Mind you, even if removing this irregularity put Nelson right over the top, I would still definitely call Scott the moral winner.
On paper FL-SEN 2018 should have been
at least Lean (closer to Likely) D.
