According to his filings, Ron Paul's investment portfolio is worth between $2.5 - 5.5 million. Not bad. What's more interesting is what he's invested in:
14% cash
20% real estate
65% gold and silver mining stocks (including, small companies, but no bullion)
For someone who believes in free enterprise, it's surprising he's not betting on the US economy. Instead, he's betting on the worst. Not much optimism there. Reagan's shining city on the hill is now Paul's black hole of Calcutta.
