There is no way a "reliable" pollster can stand on a 3 point change either way in the face of no major event. This is nuts! Rhetorical question-"Will this make as much of a spach on the MSM as yesterday's results"? We all know that answer.
Yes we do. You need look no farther than the front page headline in today's USA Today.
The polls are starting to "shift" because the MSM is now facing reality. We are getting close to the election, so the time frame for cooked numbers is passing by. They will be revising the polls little by little over the next few weeks, ultimately showing public sentiment as it really is.
Although the MSM will not hesitate to use bizarre, Dem-loaded polls to try to influence public opinion now (witness the spate of "dead heat" polls after the first debate), they cannot do so at the Election Eve if they expect to maintain any credibility with the public at large. A poll must be reasonably close to the election results if it is not to be laughed out of existence. And, since the MSM is principally a profit business, they will sell out their agenda.
