WASHINGTON—Wistfully recalling the prominence he had in previous campaign cycles, Republican presidential candidate Rick Santorum told reporters Monday that he is nostalgic for a time when his beliefs were considered outlandish enough to make headlines. “I sure do miss the days when I could steal the spotlight just by saying that I believe birth control is wrong because sex must be procreative, or that Palestinians don’t actually exist,” said Santorum, lamenting that previous comments about not wanting to improve the lives of African Americans by “giving them somebody else’s money” made him sound like just another member of the 2016 GOP pack.
