It's a shame that Sen. Lindsey Graham, who on Monday joined the burgeoning field of Republican presidential candidates, is best known for his foreign-policy stands. It's his pragmatism in domestic affairs that merits a larger audience. He provided a rare Republican vote confirming Attorney General Loretta Lynch in April, and was an unflinching supporter of the bipartisan immigration reform that passed the Senate in 2013. (Had the plan not died in the House, immigration wouldn't be so vexing to Graham's fellow Republican presidential candidates today.) Grasping the threat posed by carbon pollution, he backed a cap-and-trade initiative to establish a market for greenhouse-gas emission credits. Neither climate change policy nor immigration reform has been an especially high priority for many South Carolina Republicans. But Graham backed the proposals, reached out to make deals with senators in both parties and trusted he could sell the merits to his constituents. That's leadership. Whether it's the kind of leadership his party seeks in 2016 remains to be seen.
