Doris Kearns Goodwin To Stephen Colbert: What Obama Needs To Do Next (VIDEO)

Doris Kearns Goodwin, biographer, historian and the Pulitzer Prize winning author of "No Ordinary Time: Franklin and Eleanor Roosevelt," said to Stephen Colbert last night about President Obama, "I think he's got to smell more."

"Really?" Colbert said. "He's too sterile?"

"I think we need to see him sweating," Goodwin continued. "There's a certain thing ... What Truman was, was a fighter. You want the guy fighting. When you fight, you may have a little sweat, you may have a little smell. That would be good for him right now," Goodwin explained.

The conversation sprouted when Colbert asked Goodwin: "Anywhere in American history, has there been this kind of sweep of anger that changes the Congress?"

Goodwin explained that in 1946, as the country became displeased with President Harry Truman, the Democrats lost more seats in Congress than in this year's mid-term elections.

"But Harry was then freed to be himself," she said. "He became 'Give 'Em Hell Harry' and they eventually loved him."
