From the Boston Globe:
The survey released yesterday by the Washington-based Project for Excellence in Journalism found that 59 percent of the stories that were primarily about Bush from Oct. 1-14 were negative in tone, compared to only 25 percent of the stories about Kerry. And while 34 percent of the Kerry coverage was favorable, a mere 14 percent of the president's coverage put him in a positive light. The survey examined 817 stories from The Washington Post, The New York Times, The Columbus Dispatch, and The Miami Herald; the evening and morning news programs on ABC, CBS, and NBC; PBS's nightly newscast, CNN's ''NewsNight With Aaron Brown;" and the Fox News Channel's ''Special Report With Brit Hume."
