From the 4 September 2012 edition of NBC Nightly News:
ANDREA MITCHELL: Michelle Obama is a political superstar - much more popular than her husband. Once a reluctant campaigner, now, she is a woman with a mission.
Michelle Obama is now a political pro, her husband's best campaigner, hardly needing to practice with the Teleprompters or get a feel for the stage....In the White House, she's worked for military families, fought childhood obesity, become a regular on late night.
MICHELLE OBAMA (from CBS's "Late Show With David Letterman"): Being out there, touching people, talking to people, it really gets me focused on what we're doing and why we're doing it.
MITCHELL: And if her husband is sometimes called too cool, she is all about hugs, connecting to people with a physical embrace.
