What you fail to understand is this:
1. Polls taken this far away from the last week before the election are meaningless.
2. Assuming these polls had any meaning at all, at this point the inescapable fact is clear: HRC is far below 50% in all of them, and for no other reason than her name has been around the longest she is the titular "incumbent"
3. Her star is sinking, not rising. Meanwhile in the space of less than a month's time those who have announced are already well into the 40%'s where some started from positions in the single digits mere weeks earlier.
I doubt that Hillary even makes it to the primary; still every day she stays in the race she sucks the wind and dollars out of anyone else on the (D) side who would hope to mount a challenge.
The (D)'s have the long knives out for each other. Obama's and Clinton's hate each other as much as need each other and they will before long be turning on each other.
Wring you hands all you want over this poll nonsense. It's all a wasted effort.
You'll only be shown to be the sucker for placing so much credence in what is at this point so meaningless.
FReegards!
