Answer :
"D. His efforts to end poverty were hurt by the enormous cost of the war in Vietnam" is true. There were also political push-backs from opponents, however.
Answer:
The correct answer is D. President Johnson's efforts to end poverty through Great Society were hurt by the enormous cost of the war in Vietnam.
Explanation:
The Vietnam War was the reason why President Johnson did not stand for re-election in 1968. The protests and the decrease in his electoral image after the Tet Offensive did not give him the necessary guarantees for his re-election, even though his Great Society program significantly reduced the percentage of Americans living below the poverty line, going from 23 percent to less than 12 percent.
