FREIBURG, Germany – In a few weeks, 74-year-old Joanne Dennig will do something she has never before done – vote in an American election. "I realized that I've got to vote," said Dennig, who left her home in Minnesota and moved to Germany in 1952. With President Bush and his Democratic challenger John Kerry in a dead heat, every vote matters this year, even if it must cross the Atlantic Ocean. Dennig's paper ballot will travel 5,000 miles from her home in southwest Germany to a courthouse in Ramsey County, Minn., where she has not lived in more than a half-century.
