The study looked at how well voters remembered the policies of Trump and Clinton from the 2016 election. They found that more people could recall Trump's policies that would benefit them, suggesting his campaign did a good job of getting its message across. People who watched liberal news were more likely to remember Clinton's policies, while those who watched conservative news were more likely to remember Trump's. This shows that the type of news people watched influenced what they remembered about the candidates' policies, even after taking into account their own political beliefs and exposure to mainstream media. Overall, the study challenges the idea that campaigns don't have much impact on voters' opinions.
