In 1941 Representative from Texas's 10th district Lyndon Baines Johnson ran for the Democratic U.S. Senate nomination in a special election to replace Senator Andrew Jackson Houston (son of the famous Texas hero and statesman Sam Houston) who died on Jun. 26, 1941 in a Baltimore, Maryland hospital five days after his 87th birthday. Johnson narrowly lost the nomination (by 1,311 votes or 0.23 percent) to the sitting Governor of Texas W. Lee "Pappy" O'Daniel. O'Daniel went on to win the Texas Senate special election in a landslide victory, keeping a Democratic hold in Texas.
But what if that was all different. Say around 1,400 people decided that 32 year old Lyndon Johnson would be a better choice than Pappy O'Daniel and Johnson won the Senate eight years earlier. What if FDR decided against having Harry S. Truman as his running mate in 1944 and instead chose a young Senator from the important state of Texas by the name of Lyndon Johnson. FDR dies on time on April 12th, 1945 and is succeeded by the youngest President in U.S. history Lyndon B. Johnson.
