No editorials in the SF Bay Area for years now. The last I can recall was Ray Jacobs at KTVU. Though he was in station management, he clearly had broadcasting experience - he had a well modulated deep voice and looked very professional on camera. James Gabbert, the now retired maverick owner of KOFY TV20 used to do editorials from time to time when something was annoying him.
When threads on this subject come up, I always think of Pat Paulsen on the
Smothers Brothers Comedy Hour. Paulsen's first shot at fame arrived when he got the chance to spoof TV editorials.

By the way, I don't think the Fairness Doctrine has anything to do with the decline of TV editorials. First of all, the FD has been weakened compared to the 60s and 70s when these TV editorials were all over the place. Second, as I understand it, the FD never prevented broadcasters from giving their opinion. If it did, there wouldn't be all right-wing radio stations in every American media market.
I suspect the explanation is that broadcasting is much more corporatized than it used to be. Most editorials were about local or regional issues. These days, management isn't as interested in local issues, and doesn't want to upset the various constituencies and have to answer complaint calls and e-mails.
