Mittmentum? Ctd

Brendan Nyhan unpacks media-fueled momentum narratives:

Traditionally, campaign reporters attend campaign events and seek to infer which campaign is winning, which is losing, and why. (Dickerson’s case  that “Romney is peaking at the right time,” which acknowledges the tie in the polls, is based on enthusiastic crowds at his rallies.) Even though Obama remains in a stronger position in the Electoral College, his post-Oct. 3 strategy looks to journalists like the approach of a losing campaign, whereas Romney and his campaign aides are not just trying to convince reporters that they are surging but acting like it. When these campaign optics seem not to line up with the publicly available numbers, journalists too often discount the data, assuming that the campaigns must know something from their private polling that the media doesn’t.
