Viewers who fantasized about potshots between Sarah Palin and Katie Couric were disappointed Tuesday morning. Both women did their own thing in their respective morning-show guest spots. Palin was the much-hyped guest co-host on NBC's “Today,” going head-to-head against former “Today” anchor Katie Couric, who this week is subbing on “Good Morning America” at her current workplace, ABC. Greeting Palin, host Matt Lauer joked that as part of the “Today” team, she was briefly including herself in the “lamestream media” she often rails about. But Couric, who had a bruising 2008 interview with the then-Republican vice presidential candidate, went unmentioned. If Couric is a veteran in the morning-show world, Palin, who currently is a contributor to Fox News Channel, displayed natural poise as part of the “Today” crew. Addressing the question whether Ashton Kutcher has the acting skill to portray Apple mastermind Steve Jobs in an upcoming biopic, Palin said, “Do any of you here have experience with people being paid a lot of money to pretend like they're you?” She was talking about the recent HBO film “Game Change,” in which Julianne Moore portrayed her in the 2008 campaign. “I didn't see the movie,” the former Alaska governor hastily noted, “and I wouldn't waste my time seeing the movie.” Before stepping in as a guest co-host, Palin sat down with Lauer in the show's first hour in a more familiar role: talking about conservative politics. Though she didn't sound too excited about the prospect of Mitt Romney as the Republican presidential candidate, she insisted that anyone is better than Barack Obama in the White House.
