1968 United States presidential election

===Humphrey's comeback and the October surprise===
After the Democratic Convention in late August, Humphrey trailed Nixon by double digits in most [[Historical polling for U.S. Presidential elections#1968 United States presidential election|polls]], and his chances seemed hopeless. Many within Humphrey's campaign saw their real goal as avoiding the potential humiliation of finishing behind Wallace in the electoral college vote (if not necessarily the popular vote), rather than having any serious chance of defeating Nixon. According to ''[[Time (magazine)|Time]]'' magazine, "The old Democratic coalition was disintegrating, with untold numbers of blue-collar workers responding to Wallace's blandishments, Negroes threatening to sit out the election, liberals disaffected over the Vietnam War, the South lost. The war chest was almost empty, and the party's machinery, neglected by Lyndon Johnson, creaked in disrepair."<ref>''Time'' November 15, 1968</ref> Calling for "the politics of joy", and using the still-powerful [[Trade union|labor unions]] as his base, Humphrey fought back. In order to distance himself from Johnson, and to take advantage of the Democratic plurality in voter registration, Humphrey stopped being identified in ads as "Vice-President Hubert Humphrey", instead being labelled "Democratic candidate Hubert Humphrey".

Humphrey attacked Wallace as a racist bigot who appealed to the darker impulses of Americans. Wallace had been rising in the polls as a result of tailoring his message to audiences outside of his southern strongholds by using anti-establishment rhetoric and attacks on "concentrated wealth", with Wallace's polling numbers peaking at 21% nationally in late September and early October. However, Wallace's momentum went into reverse after he selected [[Curtis LeMay]] as his running mate. Curtis LeMay's suggestion of using tactical nuclear weapons in Vietnam conjured up the worst memories of the [[Barry Goldwater presidential campaign, 1964|1964 Goldwater campaign]].{{sfn|Perlstein|2008}} Labor unions also undertook a major effort to win back union members who were supporting Wallace, with some substantial success. Polling numbers that had showed Wallace winning almost one-half of union members in the summer of 1968 went increasingly into sharp decline as the election campaign progressed into the fall up to early November election day. As election day approached and Wallace's support in the North, Midwest and West began to wane, Humphrey finally began to climb in the polls.

In October, Humphrey—who was rising sharply in the polls due to the sharp decline of the Wallace polling—began to distance himself publicly from the Johnson administration on the Vietnam War, calling for a bombing halt. The key turning point for Humphrey's campaign came when President Johnson officially announced a bombing halt, and even a possible peace deal, the weekend before the election. The "Halloween Peace" gave Humphrey's campaign a badly needed boost. In addition, Senator Eugene McCarthy finally endorsed a vote for Humphrey in late October after previously refusing to do so, and by election day the polls were reporting a dead heat.<ref>Theodore H.
