Live, From New York: Barack Obama!
He will be joined by Democratic presidential candidate Barack Obama, who'll be jetting in from New Hampshire, PEOPLE has learned, but whose role in the show is like many of the voters he covets: undecided.
"The details of the sketch are still being worked out," an Obama campaign spokesperson tells PEOPLE.
This is not Obama's first appearance on SNL. During the primary, he appeared opposite Amy Poehler's Hillary Clinton in a skit about a Halloween costume party in which Obama came dressed as ... Barack Obama.
"I have nothing to hide," he said in the skit. "I enjoy being myself. I'm not going to change who I am just because it's Halloween."
