How about Steyn...Mark Steyn (though Ben Stein might be fun for a fill in now and then)
And she's funny, too! Have you ever heard her nighttime talk show on WABC (NYC metro area)? She and her broadcast crew have so much fun when they're on the air. They'd probably do the show even if they weren't getting paid -- it's like a party in the studio when Laura's show is broadcasting.
Also, I was just thinking about the title of O'Reilly's book, "Who's Looking out for You". Who said I need anybody to look out for me? If I did, it sure as hell wouldn't be an intellectual Lilliputian like O'Reilly.
