September 8, 2016: The US presidential race is tightening, mainly due to Clinton’s email and Clinton Foundation controversies.

A CNN/ORC poll indicates that Clinton’s email controversy is negatively impacting her chances to defeat Donald Trump in the November 2016 presidential election. Over the past month, she went from having a commanding lead over Trump to a narrow one.

In March 2015, when reporting on her email controversy began, 46 percent of registered voters agreed with the statement that her use of the server is “an important indicator of her character and ability to serve as president.” That number has risen steadily in other CNN polls to 62 percent in the most recent one.

Sixty percent also say the Clinton Foundation should be shut down either now or if she becomes president. (CNN, 9/9/2016)

The next day, the Washington Post comments on the poll results in an article with the title: “Hillary Clinton’s email server is why this race is still close.” It argues that Trump’s popularity poll numbers make him the most unpopular presidential nominee in modern history. But Clinton’s popularity has declined to be basically as bad as Trump’s. “And the reason is clear: The email story is absolutely killing her — and ruining what might otherwise be a coronation. … [I]f you look closely, perceptions about her email server track closely with her overall image and her perceived honesty and trustworthiness.” (The Washington Post, 9/9/2016)
