US Politics Feature: Santorum Springs a Surprise in Republican Primaries (Rucker/Henderson)
Rick Santorum had a breakthrough night Tuesday, winning GOP presidential contests in Missouri, Minnesota and Colorado, all of which is expected to breathe life into his struggling campaign and slow Mitt Romney’s march to the Republican presidential nomination.
The Santorum triumphs promise to, at least temporarily, alter the face of the campaign going into the crucial “Super Tuesday” contests, as the caustic tone of the primaries is expected to continue and intensify. Romney and his allies have signaled that they will use their financial advantage to launch stepped-up attacks on Santorum and on former House speaker Newt Gingrich, the other main challenger.
