When asked what might derail his agenda for his new Conservative Party government, former British Prime Minister Harold MacMillan is said to have responded, “Events, dear boy. Events.” That aptly describes how the political fortunes of war-time Presidents play out. It is surprisingly difficult for incumbent commanders-in-chief to win even if military campaigns are successful. True, Franklin Roosevelt won in 1944. But, even as the Allies were defeating the Axis powers, the popular Roosevelt won with the lowest percentage margin of victory of his campaigns. When elections occurred while the war effort appeared to be flagging, incumbents have fared badly. In 1952, as a result of the Korean War stalemate, President Harry Truman could not even win re-nomination by his own party, and the Democrats lost decisively. In a similar vein, in 1968, President Lyndon Johnson declined to pursue the Democratic Party nomination for re-election after the newscaster Walter Cronkite and other elements of the media turned the disastrous and strategic military defeat of the Viet Cong during the Tet offensive into a prevailing popular tale of American defeat.
