Which best describes hubert humphrey’s candidacy in 1968?
humphrey was hurt by his association with the adminstration’s vietnam war policy.
humphrey announced that he would end the vietnam war if elected and received strong support from the counterculture.
humphrey opposed many of johnson’s great society programs and declared he would end them if elected.
humphrey declared that the great society plan did not go far enough and proposed a radical social agenda for the democratic platform.

The correct answer is: "Humphrey was hurt by his association with the adminstration’s Vietnam War policy."

Before running for President, Humphrey was Lyndon B. Johnson's Vice President, the head of state when the Vietnam War really exploded.

Humphrey promised to end the War if he was elected, but the critics he received from his opponent, Richard Nixon, on how he poorly handled the affairs at Vietnam during his vice presidency, ultimately led him to a loss. Nonetheless, he lost the 1968 Elections by one of the smallest margins in the country's history, and some even say that he could have won if the elections would have been held a week later.

i believe your answer is d)
