In a speech this morning to the CPAC gathering in Washington, former Pennsylvania senator Rick Santorum explained that in 2004, his wife advised him against endorsing Arlen Specter, the incumbent, over Pat Toomey in Pennsylvania’s Republican senatorial primary. We all know that Santorum did end up endorsing his Senate colleague, who won reelection and later switched parties. This morning he humbly admitted: “I should have listened to my wife.” He say that this time around, he’s working to make up for that by working for Toomey “day and night.”
