First Lady's Trips Boost Health _ and Her Husband

In just the past few days, she's danced with cheering school kids, chatted with troops, swapped ideas with busy parents and engaged in a friendly cooking competition with stars from "Top Chef."

Michelle Obama's national tour was intended to promote the second anniversary of her campaign against childhood obesity. The images have been disarming, intriguing and nonpolitical, just the type of thing her husband's re-election campaign can't get enough of.

Five years to the day after Sen. Barack Obama announced he was running for president, Mrs. Obama's travels this past week offered fresh evidence of what an out-sized role she's assumed in the public eye and how powerful a political asset a first lady can be.

Make no mistake, Mrs. Obama said she's "incredibly enthusiastic" about making the case for her husband's re-election.

Simply put, "I want him to be my president for another four years," she said in a 40-minute interview Friday with a few reporters.

In recent weeks Mrs. Obama 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. Then came the tour of Arkansas, Florida, Iowa and Texas to mark the two-year-point for her "Let's Move" initiative.

The first lady draws a line between her policy efforts on childhood obesity and her political activities. But such distinctions often are lost on the public.

In an election year, it's all to the good for Barack Obama that his popular wife is traveling the country promoting can't-miss issues like healthy living.

"This is a bit of a two-fer," Mrs. Obama said in her interview on 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."

The first lady added that she knew from the beginning of her husband's presidency that she had to choose issues that were 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, Mrs. Obama also fills a more overtly political role by headlining private fundraisers that raise millions for her husband's campaign, reaching out to supporters through conference calls to various states and shooting out periodic emails to campaign backers around the country.

That part of her labors will increase considerably in the months to come.

But the first lady said she's careful to protect her time as "Sasha and Malia's mom."

"My approach to campaigning is, 'This is the time that I have to give to the campaign and whatever you do with that time is up to you, but when it's over, don't even look at me. ... No calls. No anything."

For now, the first lady's 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 that 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," Mrs. Obama told parents this past week as she chatted with them over low-calorie plates of chicken and pasta at an Olive Garden restaurant in Fort Worth. "I mean, at one point I was normal. I went to the grocery store and I did all that."

Voters typically don't pay attention to whether an event is political or not, said Democratic strategist Chris Lehane.

"They're paying attention to whether they like what they're seeing and whether they connect to it," Lehane said. Wth a first lady talking about issues that transcend the partisan divide, he said, "the mere fact that they're out there talking reflects well on their spouse."

It can't be lost on Obama's political advisers that Iowa and Florida will be strongly contested in the fall election.

While the president's favorability ratings and those of Vice President Joe Biden slipped considerably over their first three years in office, Mrs. Obama's have remained strong.

Barack Obama's favorability rating now stands at 51 percent, Biden's at 38 percent. By contrast, 66 percent of Americans have a favorable opinion of the first lady, about even with her ratings on Inauguration Day, according to the Pew Research Center.

That's about where Laura Bush stood in the fourth year of her husband's first term, and it's considerably higher than Hillary Rodham Clinton's 42 percent at the start of her husband's fourth year as president.

Mrs. Obama is particularly popular with women and younger Americans, polling shows. And she does well with the moderate and liberal Republicans and independents whom Democrats will try to lure away in the fall elections.

There are other ways to measure her appeal: Her Twitter account shot up to more than a half-million followers in less than a month. And her Facebook page has more than 6.6 million "likes."

The first lady still has her detractors. Her anti-obesity campaign has attracted some "nanny state" grumbling from conservatives who think it intrudes on personal matters.

She said Friday that the five years since her husband announced for president actually have turned her from a natural pessimist into more of an optimist, hoping to make the most of her time in the White House.

"There's a window," she said. "Whether it's four years or eight years, it's not a lot of time."

As for how she's preparing her daughters for the coming campaign, sure to be hard-fought and bitter at times, Mrs. Obama said her focus is on reassuring the girls that "whatever happens, you guys are going to be good. So don't worry about this, just focus on your world."

Preparing them for a victory or loss, she said, "I just try to play both sides of the scenario and make both sides seem great."

So far, Mrs. Obama has headlined 32 fundraisers over the past 10 months, including six this year. Tickets to her political events range from $100 to $10,000, making them more accessible than higher-dollar fundraisers for the president. And her political schedule includes smaller cities, such as Charlottesville, Va., and Cape Elizabeth, Maine, that aren't likely to draw a presidential visit.

Still, she's hauling in millions with a fundraising stump speech that mixes a recitation of administration policy initiatives with a personal sketch of her husband as a man who stays up late after the children are in bed fretting over the concerns of ordinary Americans.

It's the same humanizing role that Mrs. Obama serves regularly in her public appearances, as she mixes public policy with stories about her own family.

What parent wouldn't think it was cool when she confessed to her dinner guests at the Olive Garden that her daughters aren't that interested in the White House kitchen garden — "because anything I do they're not interested in."
