Hillary Clinton is an American politician who was the Democratic candidate for president during the 2016 U.S. presidential election. Clinton’s 2016 campaign relied heavily on the use of political polling data to determine strategy—but as a result of inaccurate poll results, Clinton overlooked campaigning in areas of the country where the data seemed to show that she was doing well. Even though nationwide public opinion seemed to indicate that Clinton would win the race against Donald Trump, Trump won the election, which shocked many people. But O’Neil asserts that a rise in populism, media skepticism, and reluctance to contribute data to polls created the illusion that Clinton was the preferred candidate.
