3. Jeb Bush
> Net worth: $19 million — $22 million

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.

2. Carly Fiorina
> Net worth: $59 million

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.

1. Donald Trump
> Net worth: $2.9 billion — $10 billion

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.
