The one effect of Korean stalemate in U.S politics was the election of Dwight D. Eisenhower was US president in 1952. Eisenhower who was wining commander of worldwar II was able to get popular belief of American people that his wining the presidental election would bring end to the Korean stalemate. He made this his agenda that if elected president he would end the war and that he would even to to Korea.
Before Eisenhower's presidency, White house had Democrat president from 1932. Already popular as war hero, Eisenhower used the conflict impasse in korea as his political agenda which led the American voters believe that he would break the deadlock. This was he was able to win the1952 presidential election over Stevenson.
