I said it in the poll thread, but it's not like it's out of the question that Demings has done to Rubio what Ryan has done to Vance all Summer.
Rubio, from what I can tell, has done little to no advertising all Summer and has only raised a fraction of what Demings has. Demings meanwhile is raking in money and seemingly has been up on TV/digital all summer long.
Unfortunately, Rubio is an incumbent with basically 100% name ID that Demings doesn't have much of an opportunity to try and define the same way Fetterman and Ryan have been able to define Oz and Vance. Demings' best bet is a reversion to the mean of sorts among the demographics that have been slipping away from the Dems in Florida in recent cycles.
