This is a nonsense poll.
One, there is no way Rubio is ahead in FL if he is down nationally by 14. FL didnt go from R+1 to R+9 or more. There is a home state advantage, but it isnt that great.
Also with Hillary polling at 56%, that is at Eisenhower landslide and closing in on Reagan landslide. Does anyone get the sense that is happening? That much support for Hillary? If she was doing that well, there wouldnt be angst among Dem party officials and liberals about her nomination.
Nobody pays attention to the specific details of a poll this far from an election.
Presidential elections in recent memory and intensely partisan affairs where the margins aren't close to this. So, it would be ridiculous to think Hillary Clinton is going to get 60% or whatever. Even if every poll at this point said she was at 60% for the general election, the race will inevitably narrow when people revert to their partisan leanings.
I think what you can say when every poll has Hillary Clinton ahead this early, is that she has an initial advantage.
