President Johnson gained more support for social reforms after what?

President Johnson gained more support for social reforms after the assassination of President Kennedy in 1963. The national mourning and desire to honor Kennedy's legacy galvanized public and congressional support for Johnson's ambitious Great Society programs, which aimed to eliminate poverty and racial injustice. This momentum helped pass significant legislation, including the Civil Rights Act and the Medicare program. Additionally, the economic prosperity of the time provided a favorable environment for implementing these reforms.
