Which group was the main target of palmer raids of 1919-1920 and the mcCarthy hearings of 1950?

The main target of the Palmer Raids of 1919-1920 and the McCarthy hearings of the 1950s was the Communist Party and individuals suspected of being communists or socialist sympathizers. During the Palmer Raids, the government sought to arrest and deport radicals, particularly immigrants, in response to fears of a communist revolution. Similarly, the McCarthy hearings aimed to root out alleged communists within the U.S. government and other institutions, reflecting the intense anti-communist sentiment of the Cold War era. Both events highlighted the broader societal fears of subversion and radicalism in America.
