Can't charge Santorum being an elitist?
Rick Santorum traveled in 2002 to Rome to speak at a centenary celebration of the birth of Saint Josemaría Escrivá, founder of Opus Dei. He and his wife were invested as Knight and Dame of Magistral Grace of the Knights of Malta in a ceremony at St. Patrick's Cathedral in New York on November 12, 2004.
Santorum's net worth has been estimated between $880,000 and $3 million, which mainly comes from five rental properties around Penn State University, two personal homes in Great Falls and Penn Hills, and some IRA accounts - Wiki
Swearing an oath to a secret society whether Catholic or not is in my book an elitist.
