LOS ANGELES (NBC News) -- The presidential campaign trail makes its way to "The Tonight Show with Jay Leno" tonight.
President Barack Obama will be Jay's guest. Gov. Mitt Romney also visited the show this year.
When it comes to political humor, Leno says he tries to be an equal opportunity offender.
"I don't think anybody can figure out my political beliefs. At least, I hope not," he says.
Leno says this year's campaign doesn't quite stack up comedically to what he calls the golden years: "Clinton and Bush, fantastic!"
And even though the candidates provide Leno nightly targets, he says it's never awkward having them as guests.
"I never question their patriotism. You just joke about their judgment. It's a bit like the Mafia. You don't go after the wives or the families," he explains.
Obama's last visit to "The Tonight Show" was almost exactly one year ago.
Romney visited during the primary season in March.
First lady Michelle Obama and the governor's wife, Ann Romney, have also been guests on Leno's show this year.
