Trump could be doing better than Hillary. We have no way of knowing. MSM election news is currently in hyper-biased propaganda mode and cannot be relied on for accuracy
As 538 demonstrated with their analysis of the 2012 election......there is a bias in the MSM when it comes to polling results:
toward the right. With all but 4 of 23 polling agencies skewing inaccurately toward the republicans. Some by as many as 5 to 7 points.
Which suggests that Trump's actual support could be significantly worse than his already horrid polling numbers would indicate.
