Hillary Clinton's arrow misses the mark: Crude 'MS Paint' logo mocked on social media for resemblance to hospital road signs, the Cuban flag and even a Hungarian fascist party

Ben Carson       Retired Physician

Age: 63

Religion:              Seventh-day Adventist

Base: Evangelicals

            Résumé: Famous pediatric neurosurgeon, youngest person to head a major Johns Hopkins Hospital division. Created a charity that awards scholarships to children of good character.

Education: B.A. Yale University. M.D. University of Michigan Medical School.

Family: Married to Candy Carson (1975), with three adult sons. The Carsons live in Maryland with Ben's elderly mother Sonya, who was a seminal influence on his life and development. 

Claim to fame: Carson spoke at a National Prayer Breakfast in 2013, railing against political correctness and condemned Obamacare – with President Obama sitting just a few feet away.

Achilles heel: Carson is inflexibly conservative, opposing gay marriage and once saying gay attachments formed in prison provided evidence that sexual orientation is a choice.

Carly Fiorina         Former CEO

Age: 60

Religion:      Episcopalian 

Base: Conservatives

                Résumé: Former CEO of Hewett-Packard, former group president of Lucent Technologies, onetime US Senate candidate in California

Education: B.A. Stanford University. UCLA School of Law (did not finish). M.B.A. University of Maryland. M.Sci. Massachusetts Institute of Technology.

Family: Married to Frank Fiorina (1985), with two adult step-daughters. Divorced from Todd Bartlem (1977-1984).

Claim to fame: Fiorina was the first woman to lead a Fortune 20 company, something that could provide key ammunition against the Democratic Partys' drive to make Hillary Clinton the first female president.

Achilles heel: Fiorina's unceremonious firing by HP's board has led to questions about her management and leadership styles. And her only political experience has been a failed Senate bid in 2010 against Barbara Boxer.

Mike Huckabee     Former Arkansas governor 

Age: 59

Religion:            Southern Baptist

Base: Evangelicals

Résumé: Former governor and lieutenant governor of Arkansas, former Fox News Channel host, ordained minister, author

Education: B.A. Ouachita Baptist University. Southwestern Baptist Theological Seminary (did not finish). 

Family: Married to Janet Huckabee (1974), with three adult children. Mrs. Huckabee is a survivor of spinal cancer.

Claim to fame: 'Huck' is a political veteran and has run for president before, winning the Iowa Caucuses in 2008 and finishing second for the GOP nomination behind John McCain. He's known as an affable Christian and built a huge following on his weekend television program.

Achilles heel: Huckabee may have a problem with female voters. He complained in 2014 about Obamacare's contraception coverage, saying Democrats want women to 'believe that they are helpless without Uncle Sugar.' And in 2015 he earned scorn for hawking herbal supplements in infomercials as a diabetes cure.

Ted Cruz            Texas senator

Age: 44

Religion:         Southern Baptist

Base: Tea partiers

                    Résumé:US senator, Texas solicitor general, US Supreme Court clerk, associate deputy attorney general under President George W. Bush

Education: B.A. Princeton University. J.D. Harvard Law School.

Family: Married to Heidi Nelson Cruz (2001), with two young daughters. His father is a preacher and he has two half-sisters.

Claim to fame: Cruz spoke on the Senate floor for 21 hours in September 2013 to protest the inclusion of funding for Obamacare in a federal budget bill.

Achilles heel: Cruz's father Rafael, a Texas preacher, is a tea party firebrand who has said gay marriage is a government conspiracy and called President Barack Obama a Marxist who should 'go back to Kenya.' 

Rand Paul      Kentucky senator

Age: 52

Religion: Presbyterian 

Base: Libertarians 

                  Résumé: US senator, board-certified ophthalmologist, congressional campaign manager for his father Ron Paul

Education: Baylor University (did not finish). M.D. Duke University School of Medicine.

Family: Married to Kelley Ashby (1990), with three sons. His father is a former Texas congressman who ran for president three times but never got close to grabbing the brass ring.

Claim to fame: Paul embraces positions that are at odds with most in the GOP, including anti-interventionist foreign policy, criminal drug sentencing reform for African-Americans and limits on government electronic surveillance.

Achilles heel: Paul's politics are aligned with those of his father, whom mainstream GOPers saw as kooky. Both Pauls have advocated for a brand of libertarianism that forces government to stop domestic surveillance programs and limits foreign interventions.

Marco Rubio         Florida senator

Age: 43

Religion:            Roman Catholic

Base: Conservatives

                  Résumé: US senator, speaker of the Florida House of Representatives, city commissioner of West Miami

Education: B.A. University of Florida. J.D. University of Miami School of Law.

Family: Married to Jeanette Dousdebes (1998), with two sons and two daughters. Jeanette is a former Miami Dolphins cheerleader who posed for the squad’s first swimsuit calendar. 

Claim to fame: Rubio's personal story as the son of Cuban emigres is a powerful narrative, and helped him win his Senate seat in 2010 against a well-funded governor whom he initially trailed by 20 points.

Achilles heel: Rubio was part of a bipartisan 'gang of eight' senators who crafted an Obama-approved immigration reform bill in 2013 which never became law – a move that angered conservative Republicans. And he was criticized in 2011 for publicly telling a version of his parents' flight from Cuba that turned out to appear embellished.

Jeb Bush, former Florida governor

Bush has a father and a brother who occupied the Oval Office, and the capacity to raise massive amounts of campaign cash. He has alienated conservatives, though, by embracing immigration reform and 'Common Core' education standards.

Chris Christie, New Jersey governor

Pugnacious and unapologetic, Christie would bring an ego-driven brashness to the race – although his abrasive style and echos of his 'Bridgegate' scandal might ultimately sink him. 

Lindsey Graham, South Carolina senator

Graham was a non-factor until a March summit in Iowa where he stole the show and put himself on the map. Arizona Sen. John McCain has praised him as the best person to help right America's foreign-relations ship 

Bobby Jindal, Louisiana governor

Jindal's main claim to fame is his strident opposition to federal-level 'Common Core' education standards, which included a federal lawsuit that a judge dismissed in late March.

John Kasich, Ohio governor

Kasich is a popular governor in the battleground Buckeye State, but has little name-recognition elsewhere. He has accommodated liberals on some issues and could be seen as a more palatable version of Jeb Bush for Republicans who are anxious about electing a family dynasty.

DEMOCRATS IN THE HUNT

Joe Biden, U.S. vice president

Biden would be a natural candidate as the White House's sitting second-banana, but his reputation as a one-man gaffe factory will keep Democrats from taking him seriously. 

Jerry Brown, California governor 

Brown has been a presidential candidate three times and earned the nickname 'Moonbeam' for his liberal policy ideas. Today he's seen as a centrist but is likely leaning against another run.

Lincoln Chafee, former Rhode Island gov.

Chafee is a Republican-turned-Democrat who has launched a presidential exploratory committee and has distinguished himself from most in his party by attacking Hillary Clinton.

Martin O'Malley, former Maryland governor

O'Malley is a guitar-playing everyman who had limited success as his state's chief executive, showing political weakness by failing to secure a victory for his hand-picked successor.

George Pataki, former New York governor

Pataki is a long shot with almost zero name-recognition outside his home state, but he pared down the size of the state government and cut taxes during 12 years in office.  He toyed with a run in 2012 but ultimately decided against it.

Rick Perry, former Texas governor

Perry was a top-tier candidate in 2012 until his 'Oops!' moment in a debate, when he couldn't remember one of his own policy positions. He now also faces a criminal indictment in Texas over tenuous claims that he abused his power.

Rick Santorum, former Pennsylvania sen.

Santorum is a perennial White House hopeful who won the GOP Iowa Caucuses in 2012 on the strength of ceaseless retail campaigning. He's best known as a religious-right crusader.

Scott Walker, Wisconsin governor

Walker built his national fame on the twin planks of turning his state's budget shortfalls into surpluses and beating back a labor union-led drive to force him out of office. Both results have broad appeal in the GOP.

Donald Trump, real estate tycoon 

Trump, the host of 'Celebrity Apprentice,' could self-fund an entire campaign without spending a life-changing portion of his net worth. He has loudly criticized President Obama and claims he can negotiate with foreign governments better than anyone else. 

Mark Warner, Virginia senator 

Warner is a former Virginia governor who won a tough Senate race in a battleground state. He's also known as a tough budget negotiator. 

Elizabeth Warren, Massachusetts senator

Warren is a populist liberal who could give Hillary Clinton headaches by challenging her from the left, but she has said she has no plans to run and is happy in the U.S. Senate.

Jim Webb, former Virginia senator

Webb is a centrist Democrat and a Reagan-appointed former Navy Secretary who's hawkish on defense policy. He has launched a presidential exploratory committee.
