4. Hillary Clinton
> Net worth: $11 million — $53 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.

Hillary Clinton is worth at least $11 million, and as much as $53 million, which includes her husband Bill’s substantial net worth. Much of the net worth Hillary is directly responsible for includes the income she earned through investments, her book, and speaking fees since her time working for 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.
