Cain casts himself as the outsider, the pizza magnate with real-world experience who&#39;ll bring fresh ideas to the nation&#39;s capital. But Cain&#39;s economic ideas, support and organization have close ties to two billionaire brothers who bankroll right-leaning causes through their group Americans for Prosperity.
