 There was surely no shortage of news this week when it came to Republicans declaring their 2016 presidential intentions, and Sen. Lindsey Graham (R-S.C.) and former Arkansas governor Mike Huckabee couldn't resist adding their names to the pile before Sunday ended. Asked on NBC’s “Meet the Press” if he had started polling voters about his chances in 2016, Graham said he is not polling, “but we set up a testing-the-waters committee under the IRS code that will allow me to look beyond South Carolina as to whether or not a guy like Lindsey Graham has a viable path.”

 “I don’t know where this will go, but I’m definitely going to look at it,” said Graham, the senior senator from South Carolina. Sen. John McCain (R-Ariz.) has been mentioning Graham as his presidential candidate of choice for ages.
– The latest Republican testing the 2016 waters is longtime Senate stalwart Lindsey Graham, who tells Meet the Press today that he's already formed a committee and that he's "definitely going to look at it." Graham, who's spent a dozen years representing South Carolina, half of those as a frequent critic of President Obama's foreign policy, says he wants to see "whether or not a guy like Lindsey Graham has a viable path" to a GOP nomination, reports Politico. "I think the world is falling apart, and I’ve been more right than wrong when it comes to foreign policy," he continues, as per the Hill. "But we’ll see." Graham has the approval of Senate BFF John McCain, notes the Washington Post; the two-time GOP nominee joked last week about his "illegitimate son," before adding "I am strongly encouraging Senator Lindsey Graham, particularly with the world the way it is today" to look into a run. Graham also has a potential rival in Mike Huckabee, who told ABC today that there's "a very strong likelihood that some time later in the spring, which has always been my timetable, I'll make some kind of a declaration and clearly state my intentions, I'll put it that way."
