American History TV continues to reair C-SPAN's history series “The Contenders,” which features profiles of key figures who ran for president and lost, but changed political history. This week, we focus on the life and career of Barry Goldwater. If history had been different, the Republican Senator from Arizona might have faced off with President John F. Kennedy in the 1964 campaign. Although ambivalent about running for president after JFK’s assassination, Goldwater was eventually persuaded by conservative activists to take up his party’s mantle. Goldwater lost in a landslide to President Lyndon B. Johnson, but he managed to change political history along the way.
