Santorum singing new tune as Iowa caucuses approach
By Paige Winfield Cunningham

Rick Santorum stumped in Sioux City, Iowa, on Sunday afternoon, striking the tone of a front-runner candidate anxious to take on President Obama after a Saturday poll indicated he could be closing in on second place.

As Mr. Santorum spoke at the Daily Grind coffeehouse, a live CNN feed played on a mounted television across from where he stood — a reminder of his new place among the top-tier candidates after surging in the polls last week.

“I’m just glad this isn’t on national television,” Sioux City pastor Cary Gordon joked after tearing up while introducing Mr. Santorum, a former senator from Pennsylvania. “How many people cry when they introduce you, Sen. Santorum?”

In a speech where he targeted the president more than any of his GOP caucus rivals, Mr. Santorum spoke glowingly of Iowa voters, asking them to “stand up for your honor” and “do your duty,” and reminding them that the stop was his 372nd town-hall meeting in Iowa.
