Total net worth: $1 to $3 million
One of the poorest 2012 candidates, Rick Santorum is still a millionaire.
Much of the former Pennsylvania senator's money is tied up in rental real estate properties, as well as education and savings plans for his children.
Santorum also has some debt to his name -- including two mortgages for rental properties totaling between $350,000 and $750,000. Those properties, located in State College, Pa., are worth between $500,000 and $1.25 million, according to the FEC filing.
From relatively modest means, Santorum served as a congressman and senator, but has since found more lucrative compensation in the private sector.
Santorum earned $1.3 million in income from January 2010 until August of last year from a variety of jobs, including a gig at the Ethics and Public Policy Center in Washington and as a contributor on Fox News.
