Barbara and Jenna Bush, the president's 22-year-old twin daughters, arrived like rock 'n' roll stars at a Republican convention party Sunday, complete with red carpet, cameras and paparazzi shouting for a smile. Inside, the guest list included actress Angie Harmon, formerly of NBC's "Law and Order," and her husband, the NFL's Jason Sehorn. Also inside was W.W.E. wrestler Chris Nowinski, who said that if he had the chance, he would tell the president's daughters there are better ways they could use their position if they really want to encourage young people to vote... Their more public, and grown-up, role has not dampened the women's high spirits. Jenna was photographed sticking her tongue out at the media during a campaign stop in Missouri, and gossip pages in New York and Washington have chronicled late-night antics including a ribald table dance (Barbara) and a lengthy public makeout session (Jenna.)
