A new poll released Thursday indicated almost two-thirds of voters continue to have a favorable view of Michelle Obama.

The first lady, known for promoting veterans issues as well as health and fitness causes from the White House, makes a positive impression among 65 percent of registered voters nationwide, according to the Marist Poll.

Twenty-three percent, meanwhile, say they have an unfavorable view of the president's wife, with 12 percent unsure about their opinion.

Her score remained steady since the group last conducted the survey in October, when 63 percent of those questioned had a favorable view, while 21 percent had a less positive opinion of Obama.

Those numbers fall higher than her husband's ratings. According to a CNN/ORC International Poll in late March, 56 percent of voters had a favorable view of President Barack Obama, while 42 percent had an unfavorable view.

"The First Lady may be the president's best asset," Dr. Lee M. Miringoff, director of The Marist College Institute for Public Opinion, said in a statement. "With numbers like these, expect her to have a high profile on the campaign trail."

The poll results came the same day as Michelle Obama's likely counterpart this fall, Ann Romney, made headlines defending herself after a top Democratic strategist and CNN political contributor accused her of being out of touch with working women.

Hilary Rosen argued Ann Romney had "never worked a day in her life" because she chose to be a stay-at-home mom, rather than enter the workforce.

Leaders from both sides of the aisle fiercely defended Ann Romney, including the first lady, who tweeted on Thursday: "Every mother works hard, and every woman deserves to be respected."
