There's an important question nagging Lindsey Graham as tries to become the first bachelor in White House since Woodrow Wilson.

Who would be his first lady?

Thinking it over, the Republican senator told Daily Mail Online: 'Well, I've got a sister, she could play that role if necessary.'

Chuckling, he added: 'I've got a lot of friends. We'll have a rotating first lady.'

Who would his first lady be? Graham says his sister, Darline, pictured with him here at his announcement rally, could serve as the face of the East Wing of the White House. 'I've got a lot of friends. We'll have a rotating first lady,' he added

His sister, Darline Graham Nordone, lives in their native state of South Carolina with her husband, Larry, and her two daughters, one from previous a marriage who is in college, and another who is in elementary school.

Her obligations to her immediate family would seemingly prevent her from Washington, D.C. to serve as the White House's full-time hostess, leading Graham to make a crack about a 'rotating first lady.'

Just two U.S. presidents were unmarried when they took office, James Buchanan and Grover Cleveland. And Cleveland later married, while in office.

Several other presidents' wives died during their residency at the White House died, some of whom remarried.

In the absence of a first lady, sisters, daughters and other relatives have fulfilled the role of hostess.

The conundrum hasn't presented itself in the last century, however. In fact, only one single man has even made an attempt at the White House, other than Graham, in modern politics.

That was Fred Karger, the little-known gays rights activist and former adviser to presidents Ronald Reagan and George H.W. Bush who sought the GOP nomination in 2012.

Graham is also running a long-shot campaign to become the Republican nominee and may never have to consider who he'd tap as White House hostess.

'Here's what I'm focused on: being president, being commander in chief,' he said, turning serious, after musing about the possibility of a 'rotating first lady.'

I've 'been knocked down enough to understand that we're all one car wreck away from needing somebody's help,' he stated, revisiting the childhood tragedies that took the lives of his mother and his father within 15 months of each other when he was in college.

After graduation, he joined the Air Force and adopted his sister so that she would receive his benefits.

'My life turned upside down. Family, friends and faith allowed me to make it,' he said. 'The last thing I'm worried about is some party at the White House.'

Later in the interview, however, he stressed that 1600 Pennsylvania Avenue would be a fun and open place if he moved in, and he'd play host regularly to his former colleagues in Congress.

'If I get to be in the White House, I'll bring Members of Congress and their families down. We''ll interact like Ronald Reagan did, we'll have a lot of chance to get to know each other,' he said. 'I'm a social kind of guy.

'I think one of the biggest mistakes President Obama made was being a little too distant.'

Graham has charmed audiences along the campaign trail both in his home state - which he's represented in Congress since 1993 - and across the nation as he runs for president by lacing his policy prescriptions with the kind of candid humor he doesn't have the opportunity to put on display in television interviews or on the Senate floor

A frequent and highly visible critic of the current occupant of the Oval Office, particularly when it comes to matters of the military, first-time attendees of a Graham event would reasonably expect him to be rough around the edges and maybe a little gruff, like his close friend John McCain, the GOP's 2008 nominee.

When it comes heavy topics such as national security Graham plays to stereotype, offering biting critiques of the Democratic president, former Secretary of State and 2016 candidate Hillary Clinton and even members of his party - namely fellow presidential candidate Rand Paul.

He's charmed audiences along the campaign trail both in his home state - which he's represented in Congress since 1993 - and across the nation as he runs for president, though, by lacing his policy prescriptions with the kind of candid humor he doesn't have the opportunity to put on display in television interviews or on the Senate floor.

'I'm actually a fun guy. I'm a lot of fun to hang around with. Just ask people who know me,' he insisted Daily Mail Online when it asked if he had any hobbies outside plotting the destruction of ISIS.

Just ask my Senate colleagues, he advised moments later. 'I think I've got a pretty good reputation of bein' easygoing.'

The 59-year-old says he got his good nature from his late father, who owned and operated a bar and pool hall.

'If you're a good owner of a bar, you make people laugh so they'll stay and drink,' Graham, a lawyer, explained. 'And you gotta be tough enough so they don't take over the bar.'

Responding to the question about what he likes to do in his increasingly limited free time, he shared that he likes to hunt and loves to go to the movies. He's also 'passionate' about golf.

'What I like most about golf is, whatever problem I have on my mind is wiped away because I can't hit this friggin' ball,' he teased.

Indicating that he likes activities that allow him to escape from the hustle and bustle of his life as a senator, and now, White House candidate, he said he enjoys going to the movie theater 'cause you're sittin' in the dark and nobody's botherin' ya.'

'Casablanca is like one of my favorite movies of all time,' he said, and when it comes to music, 'I'm stuck in the 60s and early 70s, I'm a Motown guy.'

Pets aren't his thing. 'I don't own anything you water or feed cause I'm gone all the time. I live in the back of my car.'

But he's a 'big hunter,' he reiterated. He told attendees of a Friday morning campaign event that he owns 15 guns, including an AR-15 semi-automatic rifle.

The born and raised Southerner said he also enjoys 'a good meal.'

Graham said he's had to be more selective about what he eats these days, though, as he barnstorms Iowa.

'I'm in OK shape, I used to be in pretty good shape,' he said. 'I'm low-carbin' it,' which is difficult because 'there's a carb around every corner in the campaign world.'

And 'In Iowa, you're in like the carb center of the world, but you also have a lot of meat,' he noted. 'So I should be the pork association's man of the year. I've eaten enough bacon to sink a battleship!'

He's not the only 2016 candidate opting out of carbs as a way of coping with a jam-packed campaign schedule that makes it difficult to work out.

Former Florida Governor Jeb Bush has is on a carb-free, as well. He's doing the Paleo diet and has lost weight instead of gaining it as he unofficially campaigns for the GOP nomination.

He'd dropped 30 pounds as of April, People magazine said.
