An indirect presidential election (officially the 4th Federal Convention) was held in West Germany on 1 July 1964. President Heinrich Lübke was renominated by the Christian Democratic Union. The Free Democratic Party nominated justice minister Ewald Bucher. The Social Democratic Party was divided. The official party line was that they supported President Lübke's re-election. Some have speculated this was a first move towards the grand-coalition that brought Kurt Kiesinger to power two years later. However, the high number of abstentions seems to indicate that not all members of the SPD caucus agreed with this move, as does the fact that Ewald Bucher received at least 19 votes from outside his own party.
