PARK CITY, Utah — Most people rest on the weekend. Nick Cannon has never had a more hectic, more important few days in his life. But he's loving every minute of it — and now, he's off to witness history in the making.

"We go to the premiere tonight," he said Saturday afternoon of his buzzed-about thriller, "The Killing Room," which hits Sundance just a day after Cannon and wife Mariah Carey attended the premiere of her own well-received drama, "Push."

"And then straight from the premiere, we fly to D.C.," Cannon went on. "I'm co-hosting and DJing the Neighborhood Ball — Mariah is performing. I'm also hosting and DJing a bunch of other stuff and events. I'm ready to be a part of history."

Cannon's support of Barack Obama dates farther back than those of many stars who'll be seen floating in the president-elect's orbit when he's sworn in on Tuesday. And as excited as he is to play king and queen of Hollywood with his new wife, he insisted that the next few days will be the culmination of years of hope and hard work.

"I always tell people, 'I've been down since 2004!' Ever since that great speech at the Democratic Convention," he laughed. "And this entire time, this entire campaign, I've been doing surrogate work. I've traveled everywhere from Ohio to the Carolinas to Texas, just getting out there and rooting for him. It's amazing to see it all come to fruition.

"It's a beautiful thing," he said of the new president, adding that Mariah feels the same way. "It's a time where there's a breakthrough in society — and I'm just happy to be alive."

A recent Los Angeles Times article postulated that unlike Bill Clinton, Obama is often associated with celebrities not because he hopes their "glow" will rub off on him, but the other way around — it's a point Cannon fully agrees with.

"It's true. That man is incredible," insisted Cannon, who has met Obama personally. "I'm always saying he's the same man in a room of four as he in a room of 400,000. He's so passionate, he's so giving of himself, and he's the same way, whether he's delivering a speech or talking to you one-on-one. He's an incredible dude."

Although we've all been raised to believe that being a politician means presenting different faces to different people, Cannon said that what we see of Obama is the real deal. "I've spent time with him. He's one of those people who walk in and make the room warmer," he grinned. "We've got a president who gives us [a friendly handshake]; it wasn't like a [stiff] handshake. He's like, 'Yo, what's up man, you good?' and I'm like, 'This is the leader of the free world here.' "

And since he's so tight with the new president, who's taking a short break from making major appointments, Cannon said that now might be a good time to volunteer himself for a minor position.

"I'm trying to become the official White House DJ," he laughed. Then looking straight at the camera, he addressed the president-elect directly: "I know what you like, Barack. I've rocked with you. I've DJed before, so I'm trying to get that role. We just need to get in there and set it all off."
