“There’s no education in the second kick of a mule” is a proverb meaning that one should have learned the lesson the first time. L. Mendel Rivers (1905-1970), a Democratic U.S. Representative from South Carolina, used the saying many times. There is no education in the second kick of a mule,” Rivers was quoted in The State (Columbia, SC) on March 14, 1948. Rivers didn’t support the presidential election of Harry Truman in 1948. ““There is no education in a second kick, even if the mule comes from Missouri. I hope Harry Truman doesn’t run,” rivers was quoted in the St. Louis (MO) Star-Times on March 25, 1948.
 
Rivers supported Dwight Eisenhower (a Republican) for president in 1952, but didn’t support his re-election in 1956. “No education in the second kick of a mule,” Rivers said in May 1956.
 
“There is no education in the second kick of a mule” is a popular caution against making the same mistake again, but usage is still mostly in government and politics.
 
     
Wikipedia: L. Mendel Rivers
Lucius Mendel Rivers (September 28, 1905 – December 28, 1970) was a Democratic U.S. Representative from South Carolina, representing the Charleston-based 1st congressional district for nearly 30 years. He was chairman of the House Armed Services Committee as the U.S. escalated its involvement in the Vietnam War.

Rivers’ long-held distrust of Republicans was reinforced shortly after Eisenhower became president when he ordered the desegregation of all schools on military bases and did not grant Rivers patronage privileges, despite Rivers being the only Democrat to support Eisenhower in 1952. Eisenhower’s continual push for integration infuriated Rivers. When asked if he would back Eisenhower again in 1956, Rivers later claimed to have responded “Hell no! Ain’t no education in the second kick of a mule.”
