Final answer:
The correct answer is c) The deep south alone was not enough for Goldwater to win, as Goldwater's victory in the deep south did not translate to a broader appeal, resulting in a landslide defeat in the 1964 presidential election.
Step-by-step explanation:
In the 1964 election, Barry Goldwater suffered a major defeat to Lyndon Johnson, despite winning over the deep south. This outcome suggested that the deep south alone was not enough for Goldwater to win the presidency since Johnson won every state outside of the Deep South and Goldwater's home state of Arizona, securing a landslide victory. Goldwater's stance against the New Deal and social legislation, along with his opposition to the 1964 Civil Rights Act, may have resonated in the deep south due to opposition to federal racial integration efforts, yet these views were less appealing to the broader electorate. Furthermore, Goldwater's conservative message on federal government size and power did not align with a majority of American voters at the time. The correct answer to the question is, therefore, c) The deep south alone was not enough for Goldwater to win.
