Emails taken from the inbox of John Podesta, Hillary Clinton’s campaign chair, and published this week by WikiLeaks shed light on the campaign’s efforts to confuse voters by blurring the lines between separate controversies over Benghazi and her private email use.

For example, one Oct. 2015 email from Oren Shur, Clinton’s director of paid media, showed the campaign used a focus group to test whether voters would believe their attempts to paint the two scandals as one and the same.
