Considering I can't find a single polling outfit that has polled the Florida GOP Senate race, I'd say Rubio is so far ahead that they don't even bother. So yes, that DOES mean Rubio has for all practical purposes won the primary - and he has fought long and hard for that win - something yet again you apparently don't know - and also that Rubio has held a debate, against Crist while Crist was still seeking the GOP nomination.
again I can only speak for myself, but I choose to vote for who I think would make the BEST U.S. Senator for Florida, not always the one who ran the best campaign and raised the most money... Most voters who take the time to understand the differences between Dr. Escoffery and Marco Rubio will agree that Dr. Escoffery has LIVED a conservative life longer than Marco Rubio has been alive. How important and relevant that is would be up to the individual voter.
