Here is what journalists have to say about liberal bias:
Washington Post Book World Editor Marie Arana:
"“The elephant in the newsroom is our narrowness. Too often, we wear liberalism on our sleeve and are intolerant of other lifestyles and opinions…We’re not very subtle about it at this paper: If you work here, you must be one of us. You must be liberal, progressive, a Democrat. I’ve been in communal gatherings in The Post, watching election returns, and have been flabbergasted to see my colleagues cheer unabashedly for the Democrats.”
Seattle Times Executive Editor David Boardman:
“If we wore our politics on our sleeves in here, I have no doubt that in this and in most other mainstream newsrooms in America, the majority of those sleeves would be of the same color: blue. Survey after survey over the years have demonstrated that most of the people who go into this business tend to vote Democratic, at least in national elections. That is not particularly surprising, given how people make career decisions and that social service and activism is a primary driver for many journalists.”
Juan Williams formerly of NPR:
“If you were going to events during the primaries, what you saw was that the executive editors and the top people at the networks were all rushing to Obama events, bringing their children, celebrating it, saying they were, there’s this part of history”
Washington Post reporter Thomas Edsall:
“The mainstream press is liberal…Since the civil rights and women’s movements, the culture wars and Watergate, the press corps at such institutions as the Washington Post, ABC-NBC-CBS News, the NYT, the Wall Street Journal, Time, Newsweek, the Los Angeles Times, the Boston Globe, etc. is composed in large part of ‘new’ or ‘creative’ class members of the liberal elite — well-educated men and women who tend to favor abortion rights, women’s rights, civil rights, and gay rights. In the main, they find such figures as Bill O’Reilly, Glenn Beck, Sean Hannity, Pat Robertson, or Jerry Falwell beneath contempt…If reporters were the only ones allowed to vote, Walter Mondale, Michael Dukakis, Al Gore, and John Kerry would have won the White House by landslide margins.”
New York Times Executive Editor Bill Keller:
“If the 2012 election were held in the newsrooms of America and pitted Sarah Palin against Barack Obama, I doubt Palin would get 10 percent of the vote. However tempting the newsworthy havoc of a Palin presidency, I’m pretty sure most journalists would recoil in horror from the idea.”
Jim VandeHei reporter at Politico:
“Are reporters biased? There is no doubt that — I’ve worked at the Wall Street Journal, the Washington Post, and worked here at Politico. If I had to guess, if you put all of the reporters that I’ve ever worked with on truth serum, most of them vote Democratic.”
New York Times public editor Arthur Brisband:
“So many [reporters and editors] share a kind of political and cultural progressivism — for lack of a better term — that this worldview virtually bleeds through the fabric of the Times. As a result, developments like the Occupy movement and gay marriage seem almost to erupt in the Times, overloved and undermanaged, more like causes than news subjects.”
Washington Post Ombudsman Deborah Howell:
“I’ll bet that most Post journalists voted for [Barack] Obama. I did. There are centrists at the Post as well. But the conservatives I know here feel so outnumbered that they don’t even want to be quoted by name in a memo.”
New York Times Public Editor Daniel Okrent
These are the social issues: gay rights, gun control, abortion and environmental regulation, among others. And if you think the Times plays it down the middle on any of them, you’ve been reading the paper with your eyes closed."
Newsweek’s Evan Thomas:
"There is a liberal bias. It’s demonstrable. You look at some statistics. About 85 percent of the reporters who cover the White House vote Democratic, they have for a long time. There is a, particularly at the networks, at the lower levels, among the editors and the so-called infrastructure, there is a liberal bias.
An analysis of Federal campaign contributions for people working in the newspaper and print media industries over the past 10 years found that 84% of people donating money to candidates gave money to liberal candidates.
