 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. 
 
 On NBC's "Meet the Press," Graham announced that he has set up a committee to see "whether a guy like Lindsey Graham has a viable path." 
 
 "We're not polling, but we set up a testing-the-waters committee under the IRS code," he said earlier. 
 
 The Weekly Standard reported in October that "Lindsey Graham said if he is reelected to the Senate in November, he will begin exploring a bid for the presidency." 
 
 Sen. John McCain (R-Ariz.) has been mentioning Graham as his presidential candidate of choice for ages. 
 
 "My illegitimate son Lindsey Graham is exploring that option," McCain said last week. "I am strongly encouraging Senator Lindsey Graham, particularly with the world the way it is today.” 
 
 When asked about this on NBC on Sunday, Graham joked, "The good news is I guess I'm in John's will, and I can get part of the estate." 
 
 On ABC's "This Week," Huckabee said there was "a very strong likelihood that some time later in the spring, which has always been my timetable, I'll -- I'll make some kind of a declaration and clearly state my intentions, I'll put it that way." 
 
 He said he would need to establish that his campaign could raise money better than he did in 2008 before he'd consider a run, but that he thinks the Republican field — which is almost large enough to form a football team — is "wide open." 
 
 "Anybody could be a contender, Huckabee said. "One of the things about politics, when you're actually there, you realize you're on a high wire and there is no net under you. On any given day, your campaign can implode for something that happens inadvertently or even intentionally. I mean it just happens." 
 
 On CBS's "Face the Nation," Sen. Marco Rubio (R-Fla.) was also asked about 2016. "I haven't made that decision yet," he said. ||||| Republican Sen. Lindsey Graham said on Monday that he will make his presidential ambitions known on June 1 in South Carolina. 
 
 “You’re all invited to come, spend money when you do, and I will tell you what I”m going to do about running for president,” Graham said on “CBS This Morning.” 
 
 Graham all but confirmed that he will jump in the race, saying in the interview, “I’m running because of what you see on television. I’m running because I think the world is falling apart. I’ve done more right than wrong on foreign policy. It’s not the fault of others, or their lack of this or that that makes me want to run. It’s my ability in my own mind to be a good commander in chief and to make Washington work.” 
 
 Graham teased his announcement in an email to supporters on Sunday afternoon. “As an announcement draws near, I need to know you stand with me,” Graham wrote, including a link where supporters could donate money.

 The South Carolina senator and foreign policy hawk has received support from several top donors, including billionaire Sheldon Adelson. The casino mogul co-chaired a luncheon for Graham’s PAC that immediately followed Israeli Prime Minister Benjamin Netanyahu’s March 3 speech to Congress. At the time, Graham had simply said he was “testing the waters” on 2016. 
 
 Should he declare his candidacy, Graham will enter a crowded Republican field currently lacking a presidential front-runner. But his chances of being competitive are slim. A recent NBC News/Marist poll shows that while the GOP senator is leading the field in the South Carolina primary, when it comes to all state voters, 58% think he shouldn’t even put his hat in the ring. 
 
 Graham earlier this month said he was 98.6% sure he was running. Then, just four days ago, he told South Carolina House Republicans that he was 99.9% sure.
– 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."
