Primary day at hand, fast-climbing Newt Gingrich told South Carolinians on Saturday that he was “the only practical conservative vote” able to stop front-runner Mitt Romney in the GOP presidential race. Romney acknowledged the first-in-the-South contest “could be real close” and prepared for an extended fight by agreeing to two more debates in Florida, next on the election calendar.

Former Pennsylvania Sen. Rick Santorum braced for a setback and looked ahead to the Jan. 31 contest after getting the most votes in Iowa and besting Gingrich in New Hampshire. Texas Rep. Ron Paul made plans to focus on states where his libertarian, Internet-driven message might find more of a reception with voters; his campaign said it had purchased a substantial ad buy in Nevada and Minnesota, which hold caucuses next month.
