Lyndon Baines Johnson moved quickly to establish himself in the office of the Presidency. Despite his conservative voting record in the Senate, Johnson soon reacquainted himself with his liberal roots. LBJ sponsored the largest reform agenda since Roosevelt's New Deal.
The aftershock of Kennedy's assassination provided a climate for Johnson to complete the unfinished work of JFK's New Frontier. He had eleven months before the election of 1964 to prove to American voters that he deserved a chance to be President in his own right.
Two very important pieces of legislation were passed. First, the Civil Rights Bill that JFK promised to sign was passed into law. The Civil Rights Act banned discrimination based on race and gender in employment and ending segregation in all public facilities.
Usally, by horse. (unless you are speaking of what route the would take to get places.)
