(CBS News) America's past presidents are anything but musty, half-forgotten figures for one distinguished writer. For her, they're a part of living history. Mo Rocca now, and a chat with Doris Kearns Goodwin:
"Do your kids or your husband ever say to you, 'Doris, you've got to stop living in the past'?" asked Mo Rocca.
"Every now and then," laughed Doris Kearns Goodwin," author of ""The Bully Pulpit: Theodore Roosevelt, William Howard Taft, and the Golden Age of Journalism." "I remember when I was writing 'Franklin and Eleanor Roosevelt,' and my kids said they would come by the room. And I was yelling at Franklin, 'Would you please be nicer to Eleanor!' or saying to Eleanor, 'Forget about the fact that he had an affair 20 years ago.' And they're thinking, 'What is going on in that room? She's talking to dead presidents!'"
And dead presidents have been very good to Goodwin.
All of her presidential biographies have been bestsellers. She won a Pulitzer for her book on FDR and Eleanor Roosevelt. And her Lincoln biography was the basis of the Steven Spielberg movie.
Her newest book is about the friendship between Presidents Theodore Roosevelt and William Howard Taft -- unusual for Goodwin, in that one of them is not a larger-than-life president, although he certainly was large.
"How many people are going to know much about Taft other than that he weighed 350 pounds, and he had a bathtub [that could fit four]?" said Goodwin. "And indeed, there's a picture of the bathtub with the four guys in there."
"That is a White House scandal waiting to happen," said Rocca.
The two men were a study in contrasts: Roosevelt, a contemporary wrote, barreled through life as if launched by a catapult.
"I've never written about anybody who has more energy, accomplished more," said Goodwin.
Conversely, she called Taft "the great procrastinator. He waited 'til the last minute for everything, and it got him in trouble over and over again. So I keep saying to myself when I'm about to put something off, 'I don't want to be Taft in this, I wanna be Teddy!'"
Hearing of Roosevelt's accomplishments, Rocca opined, chipped away at his self-esteem: "I mean, he does more in a page than I get done in a year," he told Goodwin.
"One of my friends thought he drank 40 cups of coffee a day -- I haven't quite confirmed that," she replied. "But he did give the slogan to Maxwell House, 'Good to the very last drop.'"
To push through his progressive agenda, Theodore Roosevelt forged a winning partnership with like-minded reporters, whom he dubbed "muckrakers." It was a time Goodwin describes as the "golden age of journalism."
"He wrote to them all the time," she said. "They were at the White House, they had lunch, they had dinner with him, they had breakfast with him."
To keep them close, Roosevelt even gave them their own White House press room.
"Lyndon Johnson used to say: 'Better to have your enemies inside the tent pissing out than outside the tent pissing in.'"
LBJ would be the first of Doris Kearns Goodwin's "guys," as she calls her presidential subjects. She would get to know him while he was still very much alive. Their relationship began when she met the president at a dance, when she was a 24-year-old White House intern. "It used to be a badge of honor to say you were a 24-year-old White House intern," she said. "It's gotten a little more complicated."
LBJ asked her to dance, then told her he wanted her to work directly for him. But there was something he didn't know:
"I'd been a graduate student at Harvard, and I wrote an anti-war, anti-LBJ piece that came out in The New Republic several days after the dance," Goodwin said.
The title of the article? "How to Remove L.B.J. in 1968."
"I was sure he'd kick me out of the program, but instead surprisingly he said, 'Oh, bring her down here for a year, and if I can't win her over, no one can.'"
What does she think Johnson saw in her? "He saw a young girl, I think, think to be honest," Goodwin said. "I mean, he was somewhat of a womanizer. But he also saw someone who loved history, he saw someone who liked to listen to him -- he loved to talk."
And Goodwin would do a lot of listening, when she moved to LBJ's ranch to help him write his memoirs after he left office.
"He couldn't sleep, and so he'd come into my room. And I would know that he was coming in so I would get up even earlier. And then he'd come into the bed, 5:00 a.m., he'd pull the sheets up. Mornings were hard for him because he was thinking about all that he had lost. And I would sit in the chair and he'd just talk to me."
