Of course any good poll for Hillary is called junk. Trump isn't going to win.
Do you really believe she's leading by 13% in Florida?
Somewhere around there. Florida votes pretty close to the country as a whole and Clinton is winning by double digits nationally. It's never made sense to me that Clinton was only up 4~ points there.
Ofc 13% is a bit on the high end but it's still in the neighborhood of what I'd expect. Personally I think Clinton will win Florida by around 9 points.
Yes, there have been a few national polls with Clinton up by double digits. You can't look at only these polls to say that's where the race is. There have also been polls that showed a very close race, and more that showed it with a moderate Clinton lead (mid to high single digits). This is exactly the spread you'd expect if she had a lead of about 6-7. Don't look at only the outliers (on either end of the spectrum); this is not being intellectually honest with yourself.
It's also unlikely that Florida will vote more Democratic than the national average. So while I do expect Clinton to win Florida, it will be by much less than double digits. Neither do I expect it to be a squeaker; if I had to pick a number, it would be (dare I say it...) 4.
