Respuesta :
The correct answer is D) Strom Thurmond took the support of the southern Dixiecrats
All Democrats didn't support Harry Truman in 1948 because Strom Thurmond took the support of the southern Dixiecrats.
In 1948, political turmoil and internal divisions in the Democratic Party hurt the possibilities of Truman for re-election. Furthermore, in July 1948, Democrats from the South formed the States Rights' Party, known by the nickname The Dixiecrats. They decided to nominate J. Strom Thurmond for President and Fielding Wright for vice president.
