Mainstream media is simply the propaganda arm of the DNC....the polls - are push polls to make it look like she is ahead in order to supress the Trump vote....
Hillary gets 200 supporters at a high school gym, Trump gets 20,000 at a stadium..... we can all do the math.
Additionally ....Recall the Brexit Polls - they predicted over and over winning by landslide - lost 48%-52%...........
The only time the pollsters care to get public opinion right is the day before the election. Until then it is all about manipulating public opinion.
Also remember they use hand counted ballots. These outrageous polls have only one purpose, to repare you for the theft of an election.
