Is Obama taking risk with prime-time program?

Barack Obama will air a 30-minute program at 7 tonight, the first time since Ross Perot that a presidential candidate has aired a prolonged campaign commercial in prime time. Based on the trailer and Obama’s campaign speeches this week, the program will make a closing argument for his campaign and will highlight everyday voters, their everyday troubles and his plans to address them, the New York Times reported. The program will also include a live broadcast from an Obama rally in Florida.
Given that Obama has a lead in polls, is the program a risk? Could it come across as over the top? A “Saturday Night Live” skit had Obama playing it safe by turning the program into a variety show that included a singing Bill Clinton.
