Some of Johnson's critics, and even some of his supporters, laughingly referred to him as "Landslide Lyndon" after some key voting districts in Texas went for he and JFK at the last moment during the election of 1960. Rumors flew around that zealous Johnson supporters, who controlled the voting apparatus in those districts, had counted the votes of deceased voters who were still, mysteriously, on the voting lists.
Some of Nixon's people urged him to fight the election results in court, given the rumors ciirculating about voter fraud in Chicago and Texas. But to Nixon's credit, he chose not to put the country through such a contentious ordeal.
