Modest Crowds
Santorum, 53, has attracted modest crowds at his events in recent days. At a weekend stop at a library, reporters and photographers outnumbered the roughly 50 people who had come to hear Santorum in Indianola, Iowa. Smaller crowds could be the result of how much time Santorum has already spent in the state. He told the Indianola audience that it was his fourth or fifth visit to the city so far in the campaign.
Joseph Vorwald, 56, a group home worker who lives there, said it was the third time he'd seen Santorum in person.
"His message rings with people," Vorwald said. "I think social conservatives will come to him because he's walked the walk and fought partial-birth abortion."
Reah Adamson, 62, an insurance company worker who lives in Carlisle, Iowa, said she plans to back Santorum. She said that's easier to do now that he's showing polling movement.
"If you're going to caucus for someone, you want to support someone who has a chance," she said.
Adamson, who came out to see Santorum this weekend before finally deciding to back him, said she is not concerned about his electability in a general election.
"I don't think it's going to matter that much," she said. "I think any of the candidates are electable."
Final Hours
As he races through the final hours before the caucuses, Santorum is telling voters to trust their own judgment and not listen to others.
