(CNN) – In an interview on John King, USA Thursday, former Pennsylvania governor and Democratic Party chairman Ed Rendell admitted to Jessica Yellin he’s uncertain whether President Obama will win this year’s election.

“He should win,” Rendell told Yellin. “He’s got the best plans for turning the economy around, and I think he’s done a good job.” Rendell continued, “He inherited the worst set of problems any president in my lifetime and he’s done a good job advancing the ball. Not as far as any of us would like, including himself. He’s done a good job.”

Rendell also wishes the Obama campaign would “get a sense of humor.”

As an example, he recounted a story from his new book, “A Nation of Wusses.” Rendell recounts his clashes with the 2008 Obama campaign.

Rendell told Yellin that during the 2008 race for the White House, he was reprimanded by Obama campaign senior strategist David Axelrod for making a joke about the president not wearing a flag pin on his lapel during the first campaign.

“I love David Axelrod, and I love Valerie [Jarrett], but they’re too serious all the time,” Rendell said.

Rendell adds the Obama camp has failed to highlight the president’s more candid, humorous side. “He tells funny stories,” Rendell said, “He's a very human, good guy. But they don't use that asset.”
