SPARTANBURG, S.C. (AP) - Republican candidates will challenge President Barack Obama on foreign policy, an issue they have given scant attention in recent weeks, in a debate Saturday night.
Two GOP rivals are fighting to mend damaged campaigns. Texas Gov. Rick Perry blundered in a debate Wednesday, when he couldn't remember a Cabinet department he's proposed to abolish. Rival Herman Cain is battling a series of sexual harassment allegations.
Their troubles leave former Massachusetts Gov. Mitt Romney in a stronger position. Former House Speaker Newt Gingrich has also seen his fortunes improve, reflected in a CBS News poll released Friday that had him tied with Romney for No. 2 behind Cain.
Also onstage will be Minnesota Rep. Michele Bachmann, Texas Rep. Ron Paul, former Pennsylvania Sen. Rick Santorum and former Utah Gov. Jon Huntsman.
