Jacob L. “Tuck” Milligan

Jacob L. “Tuck” Milligan was a Missouri congressman from Richmond whose 1934 Senate campaign made him one of Harry S. Truman’s principal opponents in a fiercely contested Democratic primary. Supported by Senator Bennett Clark, Milligan challenged the influence of the Pendergast political organization and portrayed Truman’s association with it as a liability. The race ended in a decisive Truman victory, leaving Milligan a poor third after weeks of public attacks and political spectacle.

Political Position and the Race

Milligan entered the contest with experience in Congress and a stronger statewide profile than Truman, then a county judge. Alongside John J. “Jack” Cochran, he was described as more familiar to voters with the workings of Washington. Cochran had the backing of the Igoe-Dickmann organization in the St. Louis area; Milligan’s chief political sponsor was Bennett Clark. Clark’s support placed the campaign in a larger struggle over the Pendergast organization’s hold on Missouri politics.

Milligan and Cochran opened their campaigns weeks before Truman. Both made Truman’s connection to the Pendergast organization the central vulnerability in his candidacy, depicting him as its machine candidate. The charge gained force because the organization’s conduct was again attracting lurid attention: violence in Kansas City municipal elections had left dozens injured and four people dead. In that climate, Truman was an easy target for opponents seeking to make his political backing seem disqualifying.

Attacks and Public Confrontations

At the opening of his campaign in Columbia, Truman answered the criticism by pointing to Milligan’s and Cochran’s earlier requests for, and receipt of, the Kansas City organization’s endorsement in their own congressional campaigns. He also accused Clark of seeking greater power. The exchange exposed a vulnerability in the anti-machine argument: Truman’s opponents were attacking his ties to the organization despite having previously sought its support themselves.

The attacks continued in public. The night after Johnny Lazia was shot and killed outside the Park Central Hotel, Clark spoke near St. Louis in support of Milligan, accusing Truman of attacking him rather than establishing his qualifications. Clark mocked the crowd at Truman’s Columbia rally and accused the campaign of relying on Kansas City visitors and state employees. He also ridiculed Truman’s assurances that he would not become a political boss, arguing that Truman’s record in Jackson County showed subservience to the existing boss.

At a large picnic in Clay County, Milligan and the other candidates appeared alongside Clark and Governor Guy B. Park. Milligan received the greatest applause, though Clark held the crowd’s attention. The gathering drew about ten thousand people, who sat through four hours of speeches in the sun. Its scale and reception demonstrated that Milligan’s campaign could command a substantial audience, even as the primary’s eventual results would show the limits of that support.

Milligan also attacked Truman at a banquet in his honor at the Baltimore Hotel, where seven hundred people rose to cheer him after he condemned vote fraud. He joked that if Truman reached the Senate, he would spend his time listening by long-distance telephone to his boss’s orders. The line sharpened the campaign’s central accusation: that a senator backed by the Pendergast organization would not act independently. William Hirth, president of the Missouri Farmers’ Association and a Cochran supporter, reinforced the attack by calling Truman “Tom Pendergast’s bellhop” and portraying his leap from county judge to the Senate as absurd.

The Primary Result

By the final stretch, Milligan was clearly falling behind, while Cochran and Truman appeared to be running neck and neck. On August 7, Truman won by 40,000 votes. The final count was 276,850 for Truman, 236,105 for Cochran, and 147,614 for Milligan, who finished a distant third.

The totals revealed how decisive the Jackson County result had been. Truman received 137,000 votes there, nearly half his statewide total. Two years earlier, Cochran had carried the county by 95,000 votes with Pendergast support; this time, with the organization against them, Cochran and Milligan together received only 11,000 votes. In some Kansas City precincts, Cochran received no votes at all. Cochran later believed his prediction that he would win 125,000 votes in St. Louis had spurred the Pendergast organization to work harder. His margin in St. Louis and St. Louis County was 112,000, still 25,000 below the organization’s Jackson County total for Truman.

Significance in Truman’s Political Rise

Milligan’s defeat showed the limits of a campaign built around Truman’s connection to the political machine. The attacks made that connection the defining issue of the primary, and Milligan’s backing from Clark gave the challenge a statewide political dimension. Yet Truman’s huge Jackson County margin overwhelmed the opposition. The contest also brought out a more combative side of Truman: observers accustomed to his quiet manner as a judge saw him answer attacks with sharp countercharges. Milligan’s campaign thus marked a consequential test of whether Truman could turn machine support from an apparent liability into the foundation of a statewide victory.
