Here is a quote from my online textbook [(https://online.vitalsource.com/#/books/0077024125/cfi/6/1336!/4/2/2/[email protected]:1.57) United States History and Geography by McGrall Hill Education, on page 622]

As the 1952 election approached, Americans were looking for someone or something that would make them feel more secure."
