Though Kennedy was careful to avoid overt favouritism during the 1962 Canadian election campaign, he did allow his pollster, Lou Harris, to work clandestinely for the Liberals. Several times during the campaign, Diefenbaker stated that the Kennedy administration desired his defeat because he refused to "bow down to Washington". After Diefenbaker was returned with a minority, Washington continued to press for acceptance of nuclear arms, but Diefenbaker, faced with a split between Defence Minister Douglas Harkness and External Affairs Minister Howard Green on the question, continued to stall, hoping that time and events would invite consensus.
