I jämna delstaten Iowa rings det en hel del samtal från kampanjlokaler, precis som i andra delstater. En som ringt lite mer än alla andra är Jim Murphy.
The first person to get his photo taken backstage with President Barack Obama this morning was a volunteer who has made more than 17,000 telephone calls for his re-election campaign.
Davenport retiree Jim Murphy said Obama thanked him, then posed for some snapshots shortly before taking the stage at the Mississippi Valley Fairgrounds for a 10 a.m. campaign rally. (Des Moines Register)
