A steady 40% of Americans say they have "a great deal" or "a fair amount" of trust in the mass media when it comes to reporting the news fully, accurately and fairly.

Trump is right
That gallop poll information looks quite valid and a longitudinal study has more legitimacy particularly with same question polled since the 70’s, and I believe I read it was 10,000 or 20,000 who were polled? So, a sufficient number of responses assuming they had different zip codes.
One observation about Gallup’s poll, this: in the article, they combined two responses to make a invalid statement about “four out of 10” think” which is a basically a bogus statement because they combined two possible options. If Gallop wants to keep it honest, giving a person a choice of 4 distinct answers but then merging two answers together to make either a more positive or more negative statement (in this case to make a more positive assessment) has an element of deception.
The great news is deliberately skewing information will continue to motivate more of us to continue to fight the good fight and never accept printed interpretations. More and more Americans are no longer sitting back and ingesting third party interpretations without breaking it down and making sure that the way the info presented is straightforward. Gallup needs to keep it honest, and the people will eventually decide their fate as well as all other pollster orgs.
