Republican presidential candidate Sen. John McCain, R-Ariz., waves to people on the street after holding a press conference outside Schmidt's Fudge Haus in Columbus, Ohio, Thursday, July 24, 2008. As presidential rival Barack Obama toured Berlin, McCain told reporters he would loved to give a speech in Germany. "But I'd much prefer to do it as president of the United States rather than as a candidate for president."
