In a press release designed to turn heads, the private-wealth research firm Wealth-X declares that if Hillary Clinton were to run, she would be the sixth-wealthiest candidate for president ever, with a net worth of $100 million.

Their ranking of the past candidates:

Rank Name Political Affiliation Net Worth (US$ millions)

1 Ross Perot Independent 4,300

2 Steve Forbes Republican 430

3 John Kerry Democrat 280

4 Mitt Romney Republican 220

5 Al Gore Democrat 190

I asked Wealth-X how they calculated the net worth of the candidates, and was told, โ€œWealth-X uses their own proprietary assessment of oneโ€™s wealth. Tax returns that were public would be one component of our larger methodology.โ€
