1976 жылғы ЛаРуштің президенттік науқаны және даулар

NBC reported receiving hundreds of calls protesting the broadcast. LaRouche's name was on the ballot in 23 states plus the District of Columbia on November 2, 1976. He received 40,043 votes (0.05%). U. S. Labor Party candidates sometimes received unusually high vote totals in comparison with those garnered by other small ideologically based parties. Following the election, the USLP brought lawsuits in three states challenging Carter's victory. The Republican Party joined the suits in Ohio and New York. Regional coordinator Paul Greenberg sought a recount in Milwaukee, saying "the election has actually been stolen — the actual winner was probably Jerry Ford."

In August 1977, the USLP said that the Federal Election Commission (FEC) was intentionally harassing the group as a result of a determination that forgiven debts were the equivalent of campaign contributions. The same month the USLP hired a former OSS and CIA operative, mercenary, firearms engineer and arms dealer, Colonel Mitch WerBell, to protect LaRouche. They said that LaRouche, then living in Wiesbaden, Germany, was being targeted for assassination by the "Baader Meinhof Gang", allegedly on behalf of the Carter administration. Werbell in turn recruited the chief of police from his town, Powder Springs, Georgia, to set up the security. In 1978, LaRouche began a vigorous USLP campaign for the presidency in 1980, targeting farmers, small businessmen and Teamsters Union members in the Heartland states. In May 1978, USLP Steering Committee member Elliott Eisenberg campaigned in a Chicago suburb, saying that "the reason we picked Schaumburg is because it's a relatively conservative area There's more of a tendency for people to support nuclear power." The USLP vice presidential candidate, Khushro Ghandhi, campaigned in June 1979 and predicted victory based on support from the Teamsters (a faction of the union had ties to LaRouche). Running on a pro nuclear power platform, Ghandhi said that the recent Three Mile Island accident was ordered by Energy Secretary James R. Schlesinger in order to create a false energy crisis. By late summer of 1979 the NCLC and LaRouche had decided to join the Democratic Party so that LaRouche could run for that party's presidential nomination, and the U. S. Labor Party was disbanded. In 1982 the USLP was sued for $1.5 million in damages by U. S. News & World Report when one of its employees allegedly impersonated a reporter. The magazine won an injunction against the party publications. Lyndon LaRouche, when asked about the matter, said, "I don't know anything about it and I never looked into it, but I do know that the liberal press uses undercover press practices that are abhorrent and beneath description."

The U. S. Labor Party had contacts with several notable figures on the extreme right wing of American politics. By the late 1970s, members were exchanging almost daily information with Roy Frankhouser, a government informant and infiltrator of both far right and far left groups who was involved with the Ku Klux Klan and the American Nazi Party. The LaRouche organization believed Frankhouser to be a federal agent who had been assigned to infiltrate right wing and left wing groups, and that he had evidence that these groups were actually being manipulated or controlled by the FBI and other agencies. LaRouche and his associates considered Frankhouser to be a valuable intelligence contact, and took his links to racist and anti Semitic groups to be a cover for his intelligence work. Frankhouser played into these expectations, misrepresenting himself as a conduit for communications to LaRouche from "Mr. Ed", an alleged CIA contact, who did not exist. Frankhouser was convicted in 1975 of conspiring to sell half a ton of dynamite in connection with a school bus bombing that left one man dead, and had marched on Fifth Avenue in New York wearing a Gestapo uniform. LaRouche had organized his defense campaign regarding the dynamite charges. Frankhouser asserted he was working for the government and was sentenced to five years of probation instead of the decades in prison he could have received. Frankhouser warned LaRouche in 1977 that, according to his claimed CIA contact "Mr. Ed", he was being considered for assassination, and introduced him to Mitchell WerBell III, a noted Office of Strategic Services (OSS) and Central Intelligence Agency (CIA) operative, mercenary, operator of a counterterrorism school, accused drug trafficker, firearms engineer, and arms dealer who said he had an ongoing connection to the CIA. It was WerBell who arranged for LaRouche movement members to undergo anti terrorist training. John George and Laird Wilcox say WerBell learned that the way to keep "LaRouche on the hook was to feed his monstrous ego while jerking his paranoia chain". Frankhouser cultivated a contact with a media source in New York, enabling him to tip off LaRouche about upcoming stories before they became public. Forrest Lee Fick, an associate of Frankhouser from the KKK, was added as a consultant in 1982. George and Wilcox called Frankhouser's deception "one of the biggest hoaxes in the annals of political extremism", made possible by what they called LaRouche's "obsession with conspiracy theories" and intelligence gathering. The USLP also had brief contact with the Liberty Lobby led by Willis Carto. Carto had some exploratory talks with LaRouche about a joint strategy against the IRS, but the contact was marked by much mutual suspicion. Carto was troubled by the number of Jews in the U. S. Labor Party, and by their adherence to basic socialist positions, including their support for central banking, while Labor Party members considered people in the Liberty Lobby "red necks" and "idiots".
