1. Ross Perot

Current estimated net worth: $3.58 billion

Ross Perot was one of the most popular third-party presidential candidates in U.S. history. He ran in both 1992 and 1996, but it was his first attempt at the presidency that remains most memorable.

Perot’s ornery demeanor and rootin’ tootin’ rhetoric resonated with a significant portion of the electorate, and though he didn’t win any states in the general election he garnered enough of the popular vote to suggest that quite a few disgruntled voters were out there who were fed up with both major parties.

Perot’s estimated net worth is currently $3.58 billion. Some of this wealth comes from the sale of his data processing firm, Perot Systems, to Dell in 2009, but most of it was in municipal bonds as of September.
