Diem cancelled it under the pretext that North Vietnam's communist government wouldn't keep the elections democratic; however another reason was that Ho Chi Minh was more popular than Diem and would have won the reunification election.
Ho Chi Minh had a "handle" on that program, he wasn't worried about it. It was Diem of South Vietnam who refused the elections...saying the communists might win it (something to the effect that they were fixed).
In 1954, the Vietminh forces of Vietnam defeated the French at the Battle of Dien Bien Phu, and the nation was temporarily divided into two sections, north and south. The people of the south chose Ngo Dinh Diem as their ruler and Ho Chi Minh ruled the north. Diem refused to go along with the planned elections in 1956 to unite the nation so the Vietminh members in the south created the Viet Cong and the war between north and south for control of the country began. Diem realized he would probably lose the elections. Many communists had moved south from the north and would probably not vote for Diem's regime. The US encourage Diem with aid and money. He was even considered a "George Washington of South Vietnam" by some of the American media. With US support, Diem felt he could defeat the communists so he declared a republic in South Vietnam. The government of South Vietnam requested military advisors from the United States to help train the South Vietnamese army. MrV
Ngo Dien Diem
The U.S. supported the cancellation of Vietnam's reunification elections in 1956 because it feared that the elections would lead to a victory for the communist leader Ho Chi Minh, thereby solidifying a communist government in all of Vietnam. The U.S. aimed to contain the spread of communism in Southeast Asia, aligning with its broader Cold War strategy. Additionally, the U.S. backed the anti-communist government in South Vietnam, led by Ngo Dinh Diem, which opposed the elections, asserting that they would be unfair and dominated by the North. This intervention ultimately contributed to the deepening conflict in Vietnam.
The U.S. prevented elections in South Vietnam, particularly the 1956 nationwide elections mandated by the Geneva Accords, due to concerns that the communist-led North Vietnam would win. The U.S. supported the anti-communist government of South Vietnam, led by President Ngo Dinh Diem, fearing that a fair election would undermine their geopolitical interests in Southeast Asia. U.S. officials believed that allowing elections would lead to the spread of communism, prompting their decision to intervene and promote an alternative political framework in the region.
1956.
Diem stated that elections would not being entirely free from communist influence, as the south had not been party to the 1954 Geneva peace agreements.
Ho Chi Minh had a "handle" on that program, he wasn't worried about it. It was Diem of South Vietnam who refused the elections...saying the communists might win it (something to the effect that they were fixed).
South Vietnamese President Diem postponed those elections due to excessive communist influence.
They supported Diem and Diem wouldn't win the elections because they weren't free. Ho would better win the support of the Vietnamese peasants(they knew him as Uncle Ho etc.)

I am not sure exactly what this question refers to. The US did not stop any elections during the Vietnam war. Certainly not in the United States. If the question refers to elections in Vietnam, actually in 1956 (before the US involvement), Ngo Dinh Diem stopped the elections called for in the 1954 Geneva Accords. It was only under US pressure, that he finally agreed to hold the elections which were held in 1959

The most immediate result of Ngo Dinh Diem's refusal to hold elections in South Vietnam was the escalation of political tensions and unrest, leading to increased opposition against his regime. This defiance of the Geneva Accords, which called for national elections, contributed to the rise of the Viet Cong insurgency and intensified U.S. involvement in Vietnam. Diem's actions alienated many South Vietnamese, fostering dissent and undermining his government's legitimacy.
