Obviously candid and informed, and rising fast in her field, Coaston answered a long string of my questions about her “intuitions” about the views and votes of Manhattan-Beltway media elites. It’s no surprise when a center-right conservative, or just a plain old partisan Republican, says, “The media cannot be trusted because it’s very biased to the left and an extension of the Democratic Party.” That’s dog-bites-man stuff. When a credentialed New York Times journalist provides an arsenal of ammunition for the argument, that’s worth pausing over... Coaston isn’t the first candid journalist on this subject. Some years ago, longtime Post reporter (and now New York Times opinion columnist) Thomas Edsall told me that Democrats outnumbered Republicans in newsrooms by a margin of between 15 and 25 to 1. That was in 2006. Judging by Coaston’s guesses, that margin has gotten more lopsided.
