"I want him to be my president for another four years," she said in a 40-minute interview Friday with a handful of reporters.
In recent weeks, the first lady has seemingly been everywhere: Doing pushups with Ellen DeGeneres. Serving veggie pizza to Jay Leno. Playing tug-of-war with Jimmy Fallon in the White House. And now making a rare four-state tour - to Arkansas, Florida, Iowa, and Texas - to mark the two-year point of her "Let's Move" initiative.
In an election year, it's all to the good for the president that his popular wife is traveling the country, promoting can't-miss issues like healthy living.
"This is a bit of a two-fer," Michelle Obama acknowledged in her interview Friday, "because it's an issue that I care about, and it's an issue that's important to the country. . . . I want to make sure that what I do enhances him," she said of the president.
She knew from the beginning of her husband's presidency, she said, that she had to choose issues important to her personally because "if you're just doing it for political reasons or there's some ulterior, people smell that out so easily and it's hard to sustain."
To a more limited extent, Michelle Obama also fills a more overtly political role by headlining private fund-raisers that bring in millions for her husband's campaign, reaching out to supporters through conference calls, and sending periodic e-mails to campaign backers around the country.
That part of her work will increase considerably in the months to come.
But she said she was careful to protect her time as "Sasha and Malia's mom."
For now, her most visible role is tied to her signature issue of fighting obesity, allowing her to connect with voters on an emotional level and relate to them as a mother who has struggled with some of the same challenges other families face.
"We're constantly trying to make sure that what we do is on point with what is going on in people's lives," she told parents as she chatted with them over low-calorie plates of chicken and pasta at an Olive Garden in Fort Worth.
