Billionaire Foster Friess, the conservative mega-donor who propped up Rick Santorum’s presidential campaign and suggested that women put aspirin between their knees as a form of contraception, introduced Rick Santorum at CPAC today, where he said that the former Pennsylvania senator was the most persecuted man there: “If any of us in this room has received more persecution than Rick Santorum, I don’t know who you are. This guy just knows what he believes, knows his heart and is willing to take the grief that people throw at him.”
