ABC was embarrassed last week by NewsBusters’ exposure of how their new senior medical editor, Dr. Richard Besser of the federal Centers for Disease Control, donated $400 to Barack Obama’s presidential campaign in 2008, presumably an indication of his political sympathies. An ABC News spokeswoman, Cathie Levin, defended Besser to the Associated Press, arguing that he’s a doctor “whose job it is to give impartial and unvarnished advice and he’ll be able to do the same for a television audience.”

Maybe Besser can indeed separate his political views from his reporting on health care, but a review of campaign finance records at OpenSecrets.org finds that CBS’s Dr. Jon LaPook and NBC’s Dr. Nancy Snyderman have also chipped in their own cash to Democratic — but never Republican — candidates. And both correspondents, along with Besser’s future ABC colleague, Dr. Tim Johnson, have showered the liberal Obama health care plan with fawning press. Details:

Our friends at the MRC's Business & Media Institute (BMI) have documented the media's obsession with the so-called obesity epidemic in this country. [Update: BMI's Jeff Poor wrote about this today here.]

Of course, unlike real epidemics which involve communicable diseases, obesity is not a condition you "catch" from casual, or even intimate, contact.

But as true as that is and ever shall be, it can't hurt advancing the storyline to suggest that, yes, in a manner of speaking, fatness is catchable.

The list of media-approved drinks in dwindling. Bottled water is out for its contribution to global warming, we're not supposed to chuckle at beer ads and energy drinks make kids sick according to the news media.

CBS and NBC warned of the dangers of soda, even diet soda, on July 23.

Soda "may be bad for our hearts," worried CBS "Evening News" anchor Katie Couric.

The CBS report focused on a woman "hooked" on soda, consuming eight glasses of soda a day according to CBS Medical correspondent Dr. Jon LaPook.

What CBS left out was an industry response, although the network had the opportunity. The American Beverage Association told Business & Media Institute that "Evening News" interviewed ABA president Susan Neely, but left it out of the broadcast.
