More than likely pollsters are less than truthful with voters, than the other way round. But the point is well taken.
I sometimes take a look at The Rasmussen Reports daily Presidential Tracking Poll, nothing much of note is happening there, since perhaps, oooh last April or so.
Of course CNN is right now as we talk breathlessly talking about a sudden 6% dip in Trumps numbers and 16% drop with moderates, which just smells of stupid bullshit, Trumps polls, while not particularly high have been pretty steady for nearly 2 years straight.
Nothing has happened to suddenly explain a 6% shift or a 16% drop in moderates, just the same retarded news reporting we have had for 3 years straight, anonymous source says this, rumor of tape with salacious details (again), Trump hating author releases book delivering 3rd hand accounts from people who think Trumps leadership style is nuts (who would have guessed).
