Lindsey Graham, the Republican senator from South Carolina, dies suddenly at 71, removing a senior voice on defense and foreign policy in the Senate.He has served four terms and is preparing for a fifth after a career shaped by service in the US Air Force, advocacy for the war on terror and vocal backing for Ukraine against Russia.His earlier alliance with Senator
John McCain and later alignment with
Donald Trump mirror a transformation in the
Republican Party, and his death immediately complicates succession, the state primary and the
Senate balance.
