Renaissance man Peter Thiel runs both a hedge fund and venture capital shop in Silicon Valley.
He also provided much of the dough collected by Endorse Liberty, a pro-Ron Paul super PAC that received $2.6 million from Thiel.
Thiel's political philosophy trends toward libertarianism, but his most recent mega donation went to Club for Growth, a group dedicated to smaller government that worked to defeat Sen. Dick Lugar in a GOP primary earlier this year.
The donations are just a tiny fraction of Thiel's net worth. In addition to PayPal, which he helped found, Thiel has made a few other choice business moves.
In 2004, the angel investor put up $500,000 for Facebook's first financing round. His shares are now worth closer to $1 billion.
