Former Vice President Joe Biden celebrated a win Saturday in South Carolina’s presidential primary, telling supporters: “You launched Bill Clinton, Barack Obama to the presidency. Now you launched our campaign on the path to defeating Donald Trump.” My buddy Jim Clyburn! You brought me back! Biden declared after being introduced by the S.C. congressman. “If the Democrats want a nominee who’s a Democrat-a lifelong Democrat-a proud Democrat-an Obama-Biden Democrat-then join us!” he said. “Most Americans don’t want the promise of revolution. They want more than a promise, they want results,” he also said referring to rival candidate Sen. Bernie Sanders.
