The widely played video clip of U.S. Sen. Barbara Boxer reprimanding a general for calling her "ma'am" is the gift that keeps on giving for the two Republicans hoping to challenge her next year.

Republicans Carly Fiorina and Chuck DeVore are trying to capitalize on the exchange by making it a key ingredient of their fundraising efforts and attempts to recruit grassroots support. Both campaigns say the video revs up a GOP base that already has long-standing animosity toward Boxer, among the most liberal members of the Senate.

Whether it will have currency beyond next June's Republican primary, when the winner will have to appeal to a much larger and more diverse audience, is an open question.

During a hearing last June, Boxer interrupted Brig. Gen. Michael Walsh of the Army Corps of Engineers in mid-sentence: "Do me a favor?" she said. "Could you say 'senator' instead of 'ma'am?' It's just a thing. I worked so hard to get that title, so I'd appreciate it. Yes, thank you."

Boxer said the general was not offended by her remarks, but many in the GOP clearly were, including the two Republican challengers.

Former Hewlett-Packard chief executive Carly Fiorina thought the exchange was so memorable that it prompted her to create a Web site titled CallMeBarbara.com, which she uses to raise money and keep in touch with supporters.

Campaign aides said they could not quantify the site's appeal, except to say it has received thousands of hits and led to thousands of dollars in donations.

The campaign of state Assemblyman Chuck DeVore juxtaposed the Boxer clip with an Austin Powers movie frame showing the Dr. Evil character upbraiding those who dare refer to him as "Mr. Evil." The 30-second video has generated more than 108,000 clicks on YouTube. It's been one of the campaign's most popular tools for reaching out to potential supporters.

Barbara O'Connor, professor of communications at Sacramento State University, said the use of Boxer's comments from the hearing will no doubt fire up the GOP base during the primary campaign but probably will not hurt the third-term senator in the general election. Jobs, health care and other bread-and-butter issues are expected to take precedence.

"It's not the kind of thing that plays well in California," O'Connor said, referring to the type of criticism Fiorina and DeVore are leveling at the Boxer video. "I think the economy is the sole issue that people are thinking about."

Registered Republicans represent less than a third of California's electorate. Women, who vote in greater numbers than men in California, may well see Boxer's statement as a demand for equal treatment.
