"the only First Lady since Mamie Eisenhower not to have worked outside the home"

If Ann Romney moves into the White House next year, she will be the only First Lady since Mamie Eisenhower not to have worked outside the home,

....................

But if Mrs. Romney does move into the White House next January, she will be the only First Lady born in the 20th century to have “never worked a day” in her life, as Rosen perhaps clumsily put it.

The last unemployed first lady was Mamie Eisenhower, born in 1896 and married to Ike at 19—the same age Ann was when she married Mitt. That makes Mrs. Romney as dubious an expert on the economic concerns of women as Mamie, an Army wife who moved 28 times, lived in a hotel during World War II, and played canasta and the electric organ.

Mrs. Romney said she chose to stay home and raise her five boys, but her youngest son, Craig, graduated from high school in 1999 and left for a missionary assignment in Chile in 2000. Since then, it’s been an empty nest.
