Well, who ever thought this would happen. But Hollywood’s best known Democratic liberal found herself face-to-face with her conservative Republican nemesis Dubya at the White House Sunday, and pool reporters were gleeful that President Bush gave her an awkward kiss on the cheek, and she gave him a light peck in return. When the lovefest between Bush and Babs was replayed later on video at the Kennedy Center Honors, the crowd laughed. “Art transcends politics,” Streisand had explained earlier. The Kennedy Center Honors were bestowed on her, Morgan Freeman, George Jones, Twyla Tharp, Pete Townshend and Roger Daltry. Still, Streisand told reporters that she might have preferred waiting until Obama was president. “Would have been nice,” she said. “I’m just glad he’s in.”
