Long-time conservative activist Richard Viguerie suggested today that Newt Gingrich suspend his campaign and endorse Rick Santorum in order to unite conservatives against Mitt Romney.

“Looking at last night’s numbers, it has become increasing clear that the former Speaker can either be a kingmaker or a spoiler,” Viguerie said in a statement today, “because, to unite conservatives, Gingrich would have to suspend his campaign and endorse Rick Santorum for the Republican nomination for President.” Viguerie argued that Romney must lose the nomination in order to prevent “the debacle of four more years of an Obama presidency.”
