Just one Iowan showed up at 2 p.m. campaign stop Monday at a restaurant in the unincorporated community of Hamlin, population 300, according to a report from The Des Moines Register — Peggy Toft, an insurance agent who chairs the county's Republican Party.

"We didn't have a lot of notice that he was going to be there," Toft said in a telephone interview with POLITICO, explaining the low turnout.

But even she would not endorse Santorum outright.
