WAPO TRUMPETS—“MSNBC IS SURGING”: That wouldn’t be surprising in our increasingly polarized time.   I’d be a little surprised if there weren’t at least a “surgelette.” But Exhibit 1 for the surge is this: During the week of Dec. 17, MSNBC beat Fox News for the first time in 17 years. The problem is that Sean Hannity was on vacation that week, and MSNBC beat Fox News only during the five-day work week. If all seven days of the week are considered, Fox News bested MSNBC. Consequently, I’m not sure this is quite as newsworthy as WAPO’s “media critic” thinks it is. His excitement may be another case of “Perceptions of Newsworthiness Are Contaminated by Political Usefulness Bias.”
