Michelle Obama is the most powerful woman in the world, according to Forbes magazine.
The magazine, which published its 2010 "New Forbes Power Women" story on Wednesday, named the first lady to the list's number one spot, calling her "a true change-maker" who has "given a new generation of girls and women around the world a role model."
Secretary of State Hillary Clinton also made the list's top 10, along with German Chancellor Angela Merkel, Lady Gaga, Ellen Degeneres and CEO of Kraft Foods Irene Rosenfeld.
Forbes contrasted Mrs. Obama's first lady leadership style to that of Hillary Clinton, citing her decision to "[stay] away from hard policy" as a source of her power.
"A forceful advocate of school nutrition standards and military families' affairs, she's more involved in policy than Laura Bush was," writes Forbes' Meghan Casserly. "But unlike Hillary Clinton, who championed a secretive (and ultimately unsuccessful) health care reform, Obama has stayed away from hard policy."
The first lady has become increasingly active on the campaign trail in recent weeks, rallying Democrats to get "fired up" about the issues, and warning them about the political implications of a Republican takeover of Congress in November.
"We're just beginning to see the results of our work," Mrs. Obama said during a Tuesday conference call to young supporters, href="http://www.politico.com/news/stories/1010/43247.html" >according to Politico.
"Don't stay home. Don't let frustration keep you from voting," she said, adding that change "comes about not just by hoping for it but by steady work."
Mrs. Obama has largely maintained high popularity throughout her husband's presidency, and currently enjoys a 66 percent approval rating, according to the Washington Post. (Only 44 percent of Americans say they approve of the overall job Mr. Obama is doing as president, according to .)
Starting October 13, Mrs. Obama will embark on a seven-state fundraising tour leading up to November's midterm elections.
