Murphy is still alive yet. I still believe that if Hillary wins Florida by 5, she takes Murphy along for the ride.
If Murphy wins, it will be a big steal for the Dems because he's a weak candidate, and means that the bet they made to save Gwen Graham for Governor paid off. If not, they missed a big chance to unseat Rubio and kill his star because Graham would have beaten him soundly.
Something is up with Rubio/Murphy. Rubio isn't truly pulling away yet, but the DSCC has basically already declared him the winner.
