NBC's parent company, General Electric, should send Senator John McCain flowers and a microwave oven. Tina Fey probably doesn't do a credible Mitt Romney, but her impersonation of Gov. Sarah Palin is so deliciously dead-on that it has helped "Saturday Night Live" score its highest ratings in years.
The popularity of those Palin parodies (mostly Ms. Fey quotes the Alaska governor verbatim) will surely give a boost to Ms. Fey's other job.
Her NBC comedy, "30 Rock," returns on Thursday for its third season. Despite unstinting critical acclaim and many Emmys, the show, which Ms. Fey produces, writes and stars in, alongside Alec Baldwin, has yet to be embraced by a broad audience.
