Step-by-step explanation:
Lyndon Baines Johnson, often referred to by his initials LBJ, was an American politician who served as the 36th president of the United States from 1963 to 1969. John Fitzgerald Kennedy, often referred to by his initials JFK and Jack, was an American politician who served as the 35th president of the United States from January 1961 until his assassination in November 1963. These president were both different because the roll call criteria display very little significant distinction of Kennedy and Johnson even when only controversial roll calls are selected. Kennedy's batting average and membership support is as high as Johnson's, supporting the arithmetic hypothesis. But on policy outcome measures Johnson proves far more successful, especially with respect to activism in moving a large policy agenda through Congress. That supports the legislative skill hypothesis. Combining the two results, President Johnson is judged the more effective legislative leader.
