Washington (CNN) - Pulitzer Prize-winning presidential historian Doris Kearns Goodwin notes each inauguration is moving in its own way, but only a few produce moments that are truly memorable.
"It depends upon the person and the occasion to really produce a historic inaugural speech," Goodwin said. "But the ceremony itself ... is a real tribute to the country, that a person who was the president can go out and become a private citizen (while) a new private citizen is becoming the president."
