In 1972, a power struggle rocked the Federal Republic of Germany, triggered by the Chancellor's new Eastern policy and increasing anger from the opposition. New elections were imminent. Guillaume was also part of Brandt's election campaign team. For six weeks, Guillaume accompanied Brandt on the "Vote for Willy" tour in a special train, made up to eight appearances a day, slept too little, smoked and drank too much. Despite the strain, he remained in office as Chancellor.
