Truman's wife and daughter also traveled on some of the campaign stops, and would put in an appearance with the President on the back of the train. Truman would always introduce his wife Bess as "The Boss," and his daughter Margaret as "The Boss's Boss." Truman stopped in San Antonio and met with Congressman and Senatorial candidate (and future President) Lyndon B. Johnson.
When the Democrats approved the inclusion of a civil rights plank in the party platform, many Southern Democrats walked out of the convention. They eventually ran their own slate of candidates under the "States Rights" party. Many feared the defection of the "Dixiecrats" would hurt Truman's chance to win.
On October 13, as the Presidential train traveled through Minnesota, Truman asked his aide, George Elsey, to take down some numbers. Truman calculated, in terms of Electoral College votes, how many the Democrats (White), Republicans (Black), and "Dixiecrats" (Red) would get. Truman still counted on winning.
After voting, Truman returned to his home. At around 4 in the afternoon, during the shift change of Secret Service agents, he slipped out the back door of the kitchen and into the middle of the backseat of the car with two Secret Service agents on either side and another driving. The agents drove President Truman to The Elms Hotel and Spa in Excelsior Springs, Missouri.
