Ben Quayle wins 10-candidate GOP primary

Quayle, 33, grew up in Indiana and Washington, D.C., and now works as a lawyer and managing director of a Scottsdale investment firm.

He has never held elected office, but he emerged as the top fundraiser and profited from name recognition that comes with being the son of the former Indiana senator and vice president.

One-time Defense Secretary Donald H. Rumsfeld contributed to his campaign and former President George H.W. Bush and his wife Barbara hosted a fundraiser.
