Which effect did the Vietnam War have on Lyndon Johnson's presidency?
a. Profits from the war helped funds Johnson's domestic anti-poverty programs.
b. Protests and frustration over the war led him to refuse to run for a second full term in 1968.
c. Early defeats led him to admit the war was a mistake and withdraw U.S. troops.
d. The war made him the most popular president in history when he finally left office.
"c. Early defeats led him to admit the war was a mistake and withdraw U.S. troops." would be the best option from the list, since he didn't want this to define his legacy.
