They predicted Bill McCollum would destroy Bill Nelson in 2000. What happened? With the anti-Donald Trump wave coming, I think it'll be powerful enough to wipe out Rubio, who already pretty much destroyed his career with his joke of a presidential campaign.
Unless Rubio pulls way ahead and stays there
(eg outside the MoE), the outcome of this race will probably come down to whether Hillary or Trump wins Florida, and by how much.
Not sure what to rate this as right now. I'll have to see what it looks like in September. Rubio
could be formidable, though.
