There's plenty of speculation lately about Rick Santorum's plans and some Republicans now want their party to rally around front-runner Mitt Romney. A key event could come later this month when Santorum's home state of Pennsylvania holds its primary election.

Still, Santorum has enthusiastic backers, and among them is a Louisiana businessman named Bill Doré, who contributed $1.5 million to a superPAC supporting Santorum.

Doré made his millions in the oil and gas business. His company, Global Industries, built pipelines and infrastructure offshore. Last year, a French company bought the firm. Perhaps more interesting about Doré is where he started in life.
