When Santorum endorsed Arlen Specter, he demonstrated that HE didn’t care about conservatism.
Rick Santorum has always had a secret life.
He mocked Reagan supporters in the 1980s, became pro-life to run for office in 1990, supported Specter's presidential campaign to remove life from the GOP platform in 1996.
Santorum stayed devoted to Specter, not only supporting him in 2004, but in 2010, he was also an early Mitt Romney fan, who later came out against the GOP, pro-life platform in August of 2012.
