Full list of 17 below, updated 8/10/2010. NEW UPDATE 9/14/2010 with new revolvers who don't have direct Obama ties (list at bottom of page).

The number of major media journalists who have joined the Obama administration (or now an aligned union) -- plus one who traveled through the revolving door from helping the Obama campaign into a news media slot -- is up to 15 with the news late last week that Teddy Davis, Deputy Political Director for ABC News, will be joining the left-wing Service Employees International Union (SEIU) which endorsed Barack Obama and has since worked to advance the administration’s agenda:

Four each have now revolved through ABC News and the Washington Post, three via CNN, and one each via the Chicago Tribune, Los Angeles Times, Newsweek and Time magazine. (Complete list below)

The Politico’s Ben Smith on Thursday night relayed how Teddy Davis “emails that he's leaving the network to join SEIU's already-muscular communications and politics operation” where “he'll be Assistant Director of Communications at the giant union, he said, ‘working with the SEIU team on their political campaigns and policy agenda.’”

Davis, who wrote stories for ABCNews.com, contributed to ABCNews.com’s “The Note” and occasionally conducted interviews for the online “Top Line” show, has now come full circle. His incomplete ABCNews.com bio states (jpg image): “Prior to starting law school, he served as Communications Aide and Special Assistant to the Governor of California.” ABC and Teddy Davis’s own Web site may hide the name of that Governor, but it was Democrat Gray Davis.

The ABC bio offered this description of his job: “He is responsible for helping to plan the network's political coverage on World News with Diane Sawyer, Good Morning America, Nightline, This Week and ABCNEWS.com.”

My list of 15 [UPDATED TO 16] who have spun through the revolving door between journalism and the Obama campaign, Obama administration or, in the case of Teddy Davis, into an Obama political ally:

New, UPDATED September 14, 2010:

Recent revolvers with no direct ties to the Obama administration or campaign, but who have jumped from the news media to left-wing organizations working to advance a liberal Democratic/Obama agenda:

Andrew Breslau, who for eight years ending in 2006 toiled at CNN “as a senior manager and producer,” is now President of New York City-based The Nation Institute, affiliated with the far-left The Nation magazine. Details in an August 20, 2010 BiasAlert.

Emily Lenzner, Executive Director of Communications at ABC News for its DC-based shows, who spent eight months in 2007-2008 as editorial producer for This Week with George Stephanopoulos (for whom she also toiled inside the Clinton White House), left ABC News for Anita Dunn's “strategic communications firm.” SKDKnickerbocker announced September 13, 2010 she'll be a Managing Director with the firm led by Dunn, the Obama administration's Communications Director in 2009. SKDKnickerbocker's “About” page boasts: “We helped Barack Obama by being the only firm in America to do direct mail and television advertising for his 2008 presidential victory.” Details in a September 14, 2010 BiasAlert.

Jennifer Loven, an 18-year AP veteran and the wire service's chief White House correspondent, decided to put her communications talents to work for The Glover Park Group, a DC-based “strategic communications firm” founded in 2001 by a bunch of Clinton and Gore staffers, most prominently Joe Lockhart, who found themselves unemployed after the 2000 election. She'll be “Managing Director in its Public Affairs practice.” Details in an August 12, 2010 BiasAlert.
