Nate Silver was the most conservative pollster in regards to not thinking Hillary had guaranteed wins, and he gave Trump the 30-40% change you are speaking of immediately preceding the election. However even his estimates were much farther off even 1 week before the election. That's Nate Silver, who gave Trump higher amounts of winnings compared to most other pollsters. Other pollsters were having Hillary win at even up to 95% + Big news stations did
not have the election as being very close.
Remember this map?
Who are my leaders lol? "sounds true but is not" seems like another way of saying false news?
People watch news that they think is objectively aligned with their own viewpoints. Those stations goal is to sell advertisements so you buy products. Basically news either has to be selling advertisements, or somehow sponsored/funded by other organizations who probably have their own agenda and content criteria.
