Clinton May Be Making a Big Strategic Mistake She risks 'selling past the close,' argues Dilbert creator Scott Adams By John Johnson, Newser Staff Posted Jul 28, 2016 12:42 PM CDT 379 comments Comments Is Hillary Clinton "selling past the close?" (AP Photo/Andrew Harnik, File) (Newser) – Hillary Clinton already can be congratulated on accomplishing a major feat: She's made it clear that a woman can be president, writes Dilbert creator Scott Adams on his blog. That glass ceiling is gone, whether she wins or loses in November, and "that's a big, big deal." But Adams thinks Clinton risks a big strategic mistake related to the concept of "selling past the close." It's the idea that "once the sale is made, you need to stop selling, because you have no chance of making things better, but you might give the buyer a reason to change her mind." She's already won this argument and thus there's no need to keep hammering away at it. And yet she keeps doing so, which could alienate undecided male voters in a big way. Adams contrasts the situation to President Obama's eight years ago. Generally speaking, once the public was sold on the idea that a black man could be president, he moved on to topics other than race. Clinton, on the other hand, "keeps selling," he writes. "And that’s an enormous persuasion mistake." Adams makes the scientific case that the testosterone levels of men watching the convention are surely dropping—literally. The festivities are likely making them unhappy, even if they're unsure why, and eventually they'll make the association. After all, they're observing a celebration of their "permanently diminished" role in society. All of which leaves him "wondering if this will be the first time in history that we see a candidate’s poll numbers plunge after a convention." Click for the full post.
