Between Trump and some of the other wealthier candidates like Bush and Fiorina, the 2016 Republican race may have the highest combined net worth of any primary in history. On the other end of the spectrum, however, is Wisconsin Governor and presidential hopeful Scott Walker, who appears not only to have a relatively small net worth, but also most estimates point to Walker being tens of thousands of dollars in debt. According to one source, Walker is currently paying off his credit card debt at an interest rate of close to 30%. In addition, Walker has taken on enormous student debt for his children.

As Governor, he garnered national attention by implementing right-to-work legislation, which significantly limited the power of labor unions in the state. Walker appears to be roughly in the middle of the pack for financial support among Republican candidates, raising an estimated $26.2 million.

Marco Rubio was a member of the Florida House of Representatives from 2000 to 2008. He has represented Florida in the U.S. Senate since 2010. Rubio’s estimated net worth, according to the Center for Responsive Politics, of $443,509 is low compared to other U.S. congress members, and it is nearly the lowest compared to other GOP presidential candidates. However, the Florida senator’s modest net worth has been scrutinized due to his ties with Norman Braman, a billionaire auto dealer who, in addition to funding many of Rubio’s personal endeavors, is by far Rubio’s single largest campaign donor. Large individual donations make up 70% of Rubio’s current campaign funds, which so far total around $10 million.

Bernie Sanders has an average estimated net worth of $330,507, well below other prospective presidential nominees and among the lowest compared with other members of Congress. The Vermont senator, who is the longest-serving independent in U.S. history, is a self-identified socialist. He is seeking the Democratic nomination, however, and is the most popular Democratic candidate after Hillary Clinton. In keeping with Sanders’ stated intention of starting a grassroots movement, more than 90% of his campaign contributions have come from individual donors. Sanders’ campaign speeches have drawn record numbers of attendants. Most recently, 19,000 people watched Sanders speak at an NBA arena in Portland, Oregon, the largest political event compared with all other candidates so far this election season.

Rand Paul, a Kentucky senator and ophthalmologist, is widely regarded as the most libertarian-minded presidential candidate. He, like his father Ron Paul, has long advocated for states’ right to operate without federal influence. Unlike most of his GOP running mates, the bulk of Rand Paul’s campaign contributions come from small, individual donations, which totalled more than $3.4 million as of June. While Paul is wealthier than most members of Congress, he is by no means the wealthiest. Paul’s average net worth of $1.3 million pales in comparison with that of his fellow Kentucky senator, Mitch McConnell, for example, who has an estimated average net worth of over $30 million. .

Ted Cruz, the son of a Cuban immigrant who became an oil businessman, has built his campaign around the promise of the American dream. Cruz is now an Ivy League-educated lawyer, a Tea Party-backed Texas senator, and a GOP presidential candidate. Cruz is a divisive candidate, notable for his role in the 2013 federal government shut down. He is skeptical that global warming poses a threat, is an opponent of equal marriage rights, and is also an outspoken critic of the Affordable Care Act. Far from being the wealthiest U.S. congressman, he still falls well within the top 50% with an average net worth of just over $3 million.

Mike Huckabee, the former governor of Arkansas, is running for his second presidential campaign, after losing the 2008 republican presidential primary to John McCain. Leading up to that first election, The New York Times reported that Huckabee’s assets were valued at less than $700,000. It appears that Huckabee was able to capitalize on the fame he earned during the previous race. The former governor enjoyed lucrative speaking appearances, published several books, and began hosting his own radio show on ABC. The 2016 presidential hopeful and his wife recently moved into an estimated $3 million home in Blue Mountain Beach, Florida. Huckabee’s net worth has been estimated as high as $23 million.

Ben Carson is a former neurosurgeon. He was the head of pediatric neurosurgery at Johns Hopkins for 29 years. Carson is famous for being the first to separate conjoined twins for the first time, and successfully completing other difficult surgeries. Carson has an estimated net worth of at least $8 million. Some of Carson’s wealth comes sales of the numerous books he has published, including Gifted Hands, which was adapted for a 2009 film. Carson’s income sources also include a salary from his professorship at Johns Hopkins.

Ohio Governor and presidential hopeful John Kasich remains a long shot at the moment to become the Republican nominee in 2016. Kasich is polling at an average of approximately 4%, which is 10th in the field. He has raised $11.7 million, according to The New York Times, which places him 10th among candidates of both parties for campaign finance. Before entering the realm of politics, Kasich made his living as a partner at the now infamous Lehman Brothers. Current estimates put Kasich’s net worth between $9 million and $22 million.

In 2001, Hillary Clinton became the first female senator to represent New York State. After serving as Secretary of State in the Obama administration from 2009 to 2013, Clinton announced her candidacy for president yet again this past April. Clinton is currently outspending and outpacing her closest competitor, Senator Bernie Sanders, in fundraising. The Clinton campaign has raised more than $47.5 million, not including super PAC funding, and spent nearly $18.9 million — significantly more than the $16.4 million and $4.8 million the Sanders campaign has raised and spent, respectively. However, while 69% of of Sanders’ campaign contributions have come from small individual donations, while only 17% of Clinton’s contributions have come from small individual donations.

Not including her husband’s fortune, Hillary Clinton is worth an estimated $15.3 million, much of which she earned through investments, her book, and speaking fees since her time in the government. Over the past several years, Clinton and her husband have spent hundreds of thousands of dollars on summer rentals in the Hamptons. Some of Clinton’s influential campaign donors have urged her not to rent another home in the Hamptons while campaigning for fear she could be dubbed an elitist.

Son of one former president and brother of another, former Florida Governor Jeb Bush is one of the leading GOP presidential candidates for the 2016 election. When Bush left the Florida governor’s office in 2007, he was worth an estimated $1.3 million. In his years since holding public office, between the lecture circuit and consulting jobs, Bush has amassed a small fortune. Today, Bush’s campaign aides estimate his net worth to be between $19 million and $22 million. Earlier this year, The Boston Globe reported that the former governor is having a vacation home built on a $1.4 million piece of property in Kennebunkport, Maine. Though Bush is currently trailing Trump in the polls, his campaign has raised more than $11.4 million — about six times the amount the Trump campaign has raised.

The first female CEO of a top 20 company as ranked by Fortune, Carly Fiorina is running for president under the slogan “We must once again become a nation of limitless possibility.” The former Hewlett-Packard CEO has been attempting to spin her previous experience as a qualifying credential. However, Fiorina was fired from her executive role at HP in 2005 after an ill-advised merger with Compaq and a 50% drop in the company’s stock price. Fiorina is the only woman vying for a spot on the GOP ticket and one of only two women in the entire race. In June, Fiorina claimed a net worth of $59 million. The figure includes the net worth of Fiorina’s husband, Frank. Unlike most other candidates, Carly and Frank Fiorina disclosed precise value of their assets.

Donald Trump is far and away the wealthiest individual running for the presidency. His precise net worth, however, is difficult to gauge as media estimates, his FEC financial disclosure, and statements from his own campaign vary widely. Bloomberg and Forbes estimated Trump’s net worth at $2.9 billion and $4 billion, respectively. Trump, meanwhile, claimed a net worth of $10 billion. Trump is capable of funding his entire campaign himself. So far in the campaign, he has donated $1.8 million to himself, accounting for 95% of all his campaign funds.

Trump has made numerous inflammatory remarks regarding women, immigrants, and China among other targets — remarks that have received mostly bad press but that have also helped him gain popularity. The real estate tycoon is the Republican frontrunner, commanding roughly 22% of GOP voters, roughly double the support garnered by next-in-line Jeb Bush.
