Washington ? A photo spread and interview in the August Vogue dutifully applies polish to the Bush daughters’ personas — no tabloid shots of boozy, dirty dancing here — but readers do get a hint of mother Laura’s shockingly countercultural music tastes. She sent twins Jenna and Barbara the Bob Dylan album “At Budokan” when they requested music at summer camp after sixth grade.

“Her record collection is awesome,” Jenna tells Vogue. “She’s got Jimmy Cliff and Bob Marley. When we have parties at the ranch, we play them and all our friends love it.”

Rastafari reggae in Crawford? Yah, mon!

Meanwhile, as the glamorous sistren venture out on the campaign trail, the question of their role looms. Are they going to be hand shakers? Smilers onstage who’ll stay in the background? Or will they speak to the public as surrogates of their father?

Wednesday, during a visit to a summer reading program for second-graders in Hueytown, Ala., Jenna (the blonde) helped her mother read to the children and talked with them about her plan to become a fourth-grade teacher in the fall. Then later, in Birmingham, Jenna introduced the first lady at a private fund-raising luncheon.

Barbara, who plans to work with children with AIDS, accompanied her father on his Midwestern swing, “getting a feel for the campaign, seeing what it’s all about,” as Gordon Johndroe, Laura Bush’s spokesman, put it. The 22-year-old twins are still deciding whether they want to address crowds. “It’s no small feat to introduce the president of the United States to 10,000 people — to go right from college and do that,” Johndroe told us. “That’s why they’re starting off with smaller things.”
