In 1948, president truman’s reelection was in doubt due to which of the following reasons? president truman was a republican and was opposed by a congress controlled by democrats. president truman had lost the support of the working class by not doing enough to the economy. president truman’s foreign and civil rights policies had alienated large groups of voters. president truman was prevented from seeking another term due to the provisions of the twenty-second amendment.

I believe it is "President Truman's foreign and civil rights policies had alienated large groups of voters." There was a lot of discrepancy at the time, and many people were skeptical.

In 1948, President Truman's reelection was in doubt as he had lost the support of the working class by not doing enough to help the economy.

Truman was dealing with a very complicated picture both inside and outside the United States: high inflation and food rationing were affecting American homes while a series of industrial strikes brought new fears to communism and the Soviet Union.

Despite these difficulties, and the fact that his presidency was seen as a failure, Truman's aggressive and challenging campaign turned out to be the winner, leaving everyone surprised.
