In April, there was only a 91 percent chance that Sen. Lindsey Graham (R-S.C.) would run for president of the United States. Now, he's 100 percent ready. On Monday morning, the longtime hopeful officially announced his 2016 presidential run in his hometown of Central, South Carolina. "I'm Lindsey Graham and I'm running for president of the United States," he said during the event. Graham, who has never sent an email, is a small-town boy from a blue-collar family.
