Hilary Rosen was right: Ann Romney doesn’t speak for women in the workforce.

Beltway pundit Hilary Rosen committed a mortal sin of American politics: She spoke the truth with a microphone on.

“What you have,” she told Anderson Cooper on Wednesday night, “is Mitt Romney running around the country saying: ‘Well, you know, my wife tells me that what women really care about are economic issues. And when I listen to my wife, that’s what I’m hearing.’

“Guess what?” Rosen observed. “His wife has actually never worked a day in her life.”

With that, the storm erupted.

Of course stay-at-home moms “work,” women from Barbara Bush to Michelle Obama quickly asserted. All that housekeeping and child care is a lot of work. President Obama, apparently needing more distance from Rosen’s comments, suggested Thursday that candidates’ spouses should be “off limits” altogether.

And surely, taking care of a family is hard work. In Ann Romney’s case, managing the very elaborate Romney establishment — five children,three or four houses and two Cadillacs — probably takes as much labor as most jobs in the market economy. Within 24 hours, Rosen was apologizing to all those women laboring in their homes for implying that they don’t work.

In the furor, everyone seemed to forget that unpaid mothers and household work are not what the discussion is about. Republicans are not talking about how jobs for stay-at-home moms have decreased under Obama.

They are talking about how paid work for women has suffered. Mitt Romney said this past week that 92 percent of the jobs lost under Obama were lost by women. Erick Erickson, a Republican commentator who joined Rosen on Cooper’s CNN show, argued that the president is responsible for the decline of women’s jobs in the paid workplace.

And work as she may, that’s one place Ann Romney has never been. She has spent her life in the private precincts of the marital workplace, where emotional ties replace the financial norms of the factory or office.

Now, she has emerged to campaign for her husband and to explain to him what women want. “I’ve had the fun of being out with my wife the last several days on the campaign trail,” Mitt Romney told Fox Newsthis month. “And she points out that as she talks to women, they tell her that their number one concern is the economy.”

At a recent campaign event, Romney said he wished his wife were there to help answer a question about female voters. “She says that she’s going across the country and talking with women, and what they’re talking about is the debt that we’re leaving the next generation and the failure of this economy to put people back to work.”

When Ann Romney’s husband, who faces a gender gap in some polls, uses her experience and insight as a megaphone for women’s concern over fewer paid jobs, he mistakenly assumes that all women are fungible. Which was, I take it, Rosen’s original point.

Although Ann Romney may be a fine spokesperson on some issues, the dirty little secret of angling for female votes is that while all women’s work, inside or outside the home, has the same worth, as Michelle Obama and Barbara Bush sweetly expressed, all women do not have the same interests. Women who work in the home do not have the same interest in the recovery of the formal job market as women who have to work for pay. Indeed, wage-earning women probably have more in common with their paycheck-dependent male co-workers on the subject of economic recovery than with household laborers such as Ann Romney.
