Sarah Palin will be missing from action Sunday a.m.

As is The Ticket's custom, a post listing the entire roster of appearances on this Sunday's interview programs will pop up Saturday at noon PDT (3 p.m. EDT).

But here's an advance heads up, in part because of who WON'T be found on any of the chat shows.

Three of the four now-official candidates on the major-party presidential tickets are scheduled to sit down for questions: Democrat Barack Obama on ABC's "This Week," his running mate, Joe Biden, on NBC's "Meet the Press" and Republican John McCain on CBS' "Face the Nation."

Absent from this list, of course, is the GOP's star of the moment, the not-so-long-ago obscure governor of Alaska who is McCain's running mate, Sarah Palin.

Since she was thrust onto the national stage a week ago, her appearances on it have been tightly regulated by the McCain campaign: a few side-by-side campaign stops with him and, of course, her big speech to the GOP's convention Wednesday night.
