The trust in this case is trust of strangers who are calling you to ask you polling questions.
When it comes to media, all information you consume must be read with a critical eye. You need to understand what assumptions are driving what is said, what the tone is and where they are drawing their conclusions from.
Well, so that means roughly half of the country is racist. No matter what you think of them, if you want your polls to work, this means that your polls have to also work properly on measuring the voting preferences of racists as well; a poll needs to make racists comfortable enough to reveal their intent, or it is a useless poll that won't properly reflect reality of what the people want and what the people will do.
Denouncing white supremacists after the entire country says you have to isn't really the same. Anyone with critical thinking skills can see that the number of times he has refused to denounce white supremacists or called them good people makes him a white supremacist.
It's been three years, can we please stop repeating this lie? Trump has disavowed white supremacists clearly and repeatedly, and the claim that he called them "fine people" is not true. Let me say that again: it's wrong. This is not ambiguous:
it would have taken you a single Google search to find out that when Trump talked about "fine people" at Charlottesville he explicitly said that he wasn't talking about the white supremacists and neo-Nazis and that those people should be "condemned totally." And that's just one of countless times that he's condemned white supremacists and distanced himself from them.
The media repeats this easily-debunkable falsehood again and again and again and again, people like you fall for it, and then they have the nerve to tell us that it's only the Right who engage in "misinformation".
Yea... it's so weird how Trump keeps making these, at best, ambiguous statements where he has to explain later - sometimes days later, sometimes never - what he really meant. And really weird that, during that time, neo-nazis, white supremacists, white nationals, and other groups earnestly quote those statements and publicly support him. But I guess the weirdest part is actually anyone who holds Trump accountable for those statements. /s
To continue: Promoting the birther conspiracy theory, pointedly stiffing Puerto Rico for disaster aid, racist comments about Latinos ("crime and rapists"), all the way back to the Central Park Five ad campaign, actually.
