Final answer:
The Gulf of Tonkin Resolution gave President Lyndon Johnson the power to escalate military operations in Vietnam without seeking a specific congressional declaration. It did not directly contribute to Johnson's victory in the 1964 elections.
Step-by-step explanation:
The Gulf of Tonkin Resolution was a congressional approval that gave President Lyndon Johnson the power to escalate military operations in Vietnam.
It passed with nearly unanimous support in 1964, following reported attacks on US warships in the Gulf of Tonkin.
The resolution allowed Johnson to declare war without seeking a specific congressional declaration.
However, it did not directly contribute to Johnson's victory in the 1964 elections, and instead led to increased opposition to the war as it continued.
