Despite wielding significant influence in Washington, Lindsey Graham's legacy also reveals the limits of individual power in U.S. politics

Senator Lindsey Graham has died. But what did his neoconservatism and hawkishness have to do with his home state of South Carolina?

Graham died Saturday, aged 71, following what his office described as a “brief and sudden illness.” His office did not immediately disclose an official cause of death.

Graham's death leaves a major void in GOP foreign policy, raising questions about who will champion a more interventionist role in foreign affairs.
