Lindsey Graham is no one’s idea of a hot presidential candidate. Pulling in 1 percent support in the mid-February CNN/ORC International poll of prospective Republican nominees, he’s at the very bottom, alongside Carly Fiorina and Bobby Jindal. But South Carolina’s senior senator has an edge that the rest of 2016’s prospective Republican candidates lacks: the authority to clean up after eight years of Obama-made U.S. foreign policy.

The name of Graham’s testing-the-waters presidential committee, Security Through Strength, is a summation of his worldview. Alongside his mentor John McCain, Graham has been the most prominent critic of the White House’s rapprochement with Syria and Iran, and his foot-dragging in the campaign against the Islamic State in Iraq and Syria (ISIS). Graham’s often lonely crusade of hammering the president as disengaged and weak is proving remarkably prescient. The Obama Administration’s refusal to acknowledge the epidemic of ISIS and Al Qaeda-made violence as spawning from radical Islam has turned out the lights on its post-Bush foreign policy credibility. The CNN poll mentioned above finds that 57 percent of voters disapprove of the job Obama is doing on foreign affairs, a 15-point increase from two years ago. This is in the context of a recent modest uptick in the president’s overall approval rating.
