As Obama Accepts Offers, Late-Night Television Longs for Romney The week after the first presidential debate, with Mitt Romney riding a surge in the polls, Lorne Michaels believed he was close to achieving one of the perennial objectives of an election year for the celebrated television show he created and still produces, "Saturday Night Live." Landing a presidential nominee as a guest. The excitement at the show about a possible walk-on by Mr. Romney was tangible. But sometime that Friday, interest from the Romney camp cooled; the Republican candidate did not follow the precedent set in other recent presidential races by John McCain and George W. Bush by appearing on television's most famous address for political satire. A deal with the Romney camp has not been as close since, though Mr. Michaels said he is keeping offers open to both campaigns for a last-second appearance. That happened four years ago when Mr. McCain appeared as a guest three days before Election Day, performing a memorable sketch with Tina Fey as Sarah Palin, spoofing a home shopping appearance in a late appeal for cash. Mr. Michaels is hardly alone in his pursuit: every other late-night television producer has been chasing Mr. Romney for weeks to try to secure a guest appearance, with no success so far. Mr. Romney also has declined invitations from a host of other media outlets who have landed President Obama for interviews, including MTV and NBC News, which was given two days of access to the president during his campaign tour last week. The opposite has been true for President Obama, who has taken advantage of the open invitation from the late-night shows to make extended guest appearances on Jon Stewart's "Daily Show" on Comedy Central, and Jay Leno's "Tonight Show" on NBC, racking up strong ratings in each case. Michelle Obama visited Jimmy Kimmel on ABC. Mr. Obama visited David Letterman on CBS last month and did a sketch, "Slow Jammin" the News," with NBC's Jimmy Fallon in April. In the waning days of an intensely close election, one campaign has clearly made a calculation that the late-night audience is valuable and worth courting, while the other has maintained late-night silence. Ben LaBolt, a spokesman for the Obama campaign, said the willingness to appear with interviewers like Mr. Stewart, Mr. Leno and Mr. Letterman has to do with reaching out in less conventional ways to undecided voters. "Most regular viewers of the news made up their minds a long time ago," Mr. LaBolt said in an e-mail message. So while the president has continued to do interviews in traditional news venues, our goal in the final days of the race must be to reach voters where they are - whether that's crisscrossing the country asking for their vote or appearing on the programs they tune into on a daily basis. Appearing with Mr. Stewart had the benefit of playing to an especially concentrated group of younger adults. "The Daily Show" scores the best ratings in late night among the 18- to 49-year-old viewers so valuable in television. Those viewers are hard to reach on news programs. Mr. Obama's appearance drew the biggest audience on "The Daily Show" this year, 2.8 million. Mr. Stewart's network, Comedy Central, coincidentally released a research study this month that asked so-called millennials in what venue they would most like to hear a candidate be interviewed. By a large margin they responded: on a late-night comedy show. Appearing with Mr. Leno (where he lifted "The Tonight Show" audience average by almost 50 percent), the president gained another advantage, according to a producer of one rival late-night show. "Jay is Ohio," the producer said, asking not to be identified discussing a competitor's strengths. Mr. Leno has always projected a more mid-American appeal than most other late-night hosts, a conclusion borne out by some numbers. Mr. Leno averages a 3 rating in Cleveland, but only a 2.1 in New York. Mr. Obama seemed well-aware of the potential to score with Ohio voters, when he joked with Mr. Leno about how Halloween would be different his year from last when Mrs. Obama offered trick-or-treaters only fruit. Candy for everybody! Mr. Obama joked, adding that if a child could prove he was from Ohio, he would get an extra-large Hershey bar.
