Two Clintons. 41 Years. $3 Billion.

Over four decades of public life, Bill and Hillary Clinton have built an unrivaled global network of donors while pioneering fundraising techniques that have transformed modern politics and paved the way for them to potentially become the first husband and wife to win the White House.

The grand total raised for all of their political campaigns and their family’s charitable foundation reaches at least $3 billion, according to a Washington Post investigation.

Their fundraising haul, which began with $178,000 that Bill Clinton raised for his long-shot 1974 congressional bid, is on track to expand substantially with Hillary Clinton’s 2016 White House run, which has already drawn $110 million in support.
