… The campaign press more or less openly confesses to a certain type of bias: rooting for the story. Inevitability makes for a really boring story, especially when it involves a figure like Clinton who has been in public life for so long.
Instead, the media wants campaigns with lots of “game changers,” unexpected plot twists and photo finishes. If the story isn’t really there, the press can cobble one together by invoking fuzzy concepts like “momentum” and “expectations,” or by cherry-picking polls and other types of evidence. The lone recent poll to show Sanders ahead of Clinton in New Hampshire made banner headlines, for example, while the many other polls that have Clinton still leading, or which show Sanders’s surge slowing down in Iowa and nationally, have mostly been ignored.
As a result, the flow of news that Americans are getting about Clinton is quite negative. CONT.
