It’s worth noting Scott had two fairly narrow wins in massive GOP waves. Now, Irma has helped him recover, of course, but I’m still not taking this anywhere other than Lean D.
Scott was "underwater" in his first four years as Governor in Florida YET he still managed to win Re-Election.
His Favorability Rating according to the 2014 Exits was 44/54 closerly mirroring his JA. Everyone knew Crist wasn't going to win because he was a Turncoat. Same with Fitzgerald in Ohio.
Democrats did poorly in Florida in recent years. The only victories they have had were the POTUS Victories by Obama and Nelsons in 2006 & 2012.
The last 3 Elections Bill Nelson has had badly damaged Opponents:
2000 he won against the House Impeachment Man Bill McCollum
2006 he won against Katherine Harris who was damaged goods after the Florida 2000 Recount Fiasco and how she handled it.
2012 Connie Mack was a big Flop
This Race will be a real Test for Nelson if Scott runs. Nelson will not get an "Get Out-of-Jail Free Card Run" this time.
