Alexander Burns at Politico:
Social conservative leader Gary Bauer will endorse Rick Santorum for president this weekend, a Santorum campaign source confirmed.
The endorsement, which was first reported by the Washington Post, will come during Santorum's planned visit to South Carolina.
The support from Bauer, a former Family Research Council leader who ran for president in 2000, may help Santorum position himself as the consensus Christian conservative candidate in the GOP field.
Bauer is one of a number of social conservative solons who have conferred in recent days in an attempt to coalesce behind a single Republican White House hopeful.
