Step-by-step explanation:
Truman had several advantages when it came to public opinion. One advantage was that he wisely avoided making public statements about military leadership, allowing General MacArthur to receive praise for his decades of service. Additionally, Truman's decision to replace MacArthur with Ridgeway was supported by Congress, which helped restore Truman's public image. Truman also successfully mobilized frustrated voters in the 1948 election, appealing to their desire for a change from the 'do nothing' politicians in Washington.
