'Might' being the key word in both instances. These early polls aren't meaningless like some on this forum are saying.
There was the very real potential for Michigan to go Republican in 2014, there was a genuine Democrat weakness that Land squandered. Similarly, there is the potential for Hillary to do very well in Florida, whether or not that potential is realized is another question.
This. Early polls aren't the end all be all, but they aren't completely useless like the Hillary haters tell themselves to feel better either.
