There are pretty definite limits to how much polls can actually influence an election. Not arguing the data aren’t pretty much fabricated, but...
There are probably VERY few people inclined to vote for Trump who would change their vote based on ANY poll.
OTOH polls showing Clinton far ahead could backfire badly two different ways:
- there’s the effect that people have been known to vote for the OPPOSITE party’s Senatorial candidate when they are sure of the outcome of the President; think people who loath Trump more than Hillary but don’t trust her much so they want a Republican Senate.
-and then there is the group that will only vote if it’s close, polls that show a Clinton blow-out are perhaps as likely to hurt her campaign as help.
Just a few other considerations that might annoy people left *or* right
Arizona just voted two for Trump
They actually don't think they are going to lose.
They were shocked when Brexit passed.
Never underestimate the ability of the Left to stay delusional.
