If anyone should be naturally equipped to make a great showing on a talk show, it’s a career politician several months into a national campaign. They’re rehearsed and experienced, with a ton of anecdotes at their fingertips, plus ample prepping by a squad of professionals behind the scenes. We expect them to be relaxed, witty, informed and on their game

Senator Hillary Clinton fulfilled all expectations when she swept onto The Tonight Show in her customary pantsuit, topped in bright red to up the energy quotient. She pre-empted any questions on her recent “misspeaking” about her experiences in a Bosnian landing zone and confessed, “Obviously, I had a lapse.”

When Hillary and Jay went after the serious subjects, she delivered her opinions with a humorous slant, proclaiming, “It’s the economy, stupid – and unfortunately it’s a stupid economy.” When Leno brought up Chelsea, noting, “She said you would make a better president than her dad,” Hillary had a perfect comeback, “Oh, she’s such a smart young woman.”

Her natural gesturing kept the visual energy high and she made an excellent connection with her host. Her body language was solid, as she leaned in toward Leno and patted his desk to make her points. But she barely misses a 5 Whisper rating because she failed to maintain eye contact consistently. This appearance was marred by an annoying habit of looking at the floor for long stretches, making it impossible for the camera to find her and keeping the viewer from making a connection. If she could direct some of that eye line to the crowd, she would have aced our scoreboard.

William Safire is a brilliant observer of the political scene, a legendary speechwriter and a Pulitzer Prize-winning columnist. Your average Daily Show viewer might – just might – know him as the author of Nixon Vice-President Spiro Agnew’s famous putdown of the press as “nattering nabobs of negativism.” A fact that apparently so enamored Jon Stewart, he was probably an easy booking on the show. However as a guest, Safire na-bobbled the assignment quite thoroughly.

Plugging an update of his classic book, “Safire’s Political Dictionary,” his exchanges with host Jon Stewart had as much electricity as your standard dictionary. When telling a story, he wandered all over the place, taking forever to make a simple point. Stewart was working overtime, desperately trying to turn the interview into something entertaining with barrages of gags, even interrupting and trying to save Safire’s creaky comments at times.

Further proof that Safire was in the wrong place at the wrong time was his failure to actually promote his book with any conviction. It took Stewart piling on superlatives at the end to get the message out. Clearly being a master of the printed word isn’t enough to carry the day under the relentless glare of TV. Bill stick to the typewriter…er, uh…computer!
