Who did he run against?

Answer 1

I see in the Question History that several questions (originally asking abeout different people) have been combined into one question. What I am reading above now is "Who did he run against?" so it is not clear who "HE" is.

In one original version the reference was to Adlai Stevenson. Stevenson ran against Dwight Green for governor of Illinois, and won. Later, as the Democrat nominee for President of the U.S., Stevenson ran against Dwight D. Eisenhower and lost. Later still, Stevenson ran in the primary to become the Democrat nominee for President, and was defeated by John Kennedy.
