DES MOINES - Jeremy Davis was driving past lush Iowa pastures on his way home from work one recent afternoon when his cellphone rang.
He didn't recognize the number. But Davis, a farm-bred Republican newly elected to the Ames City Council, answered.
"Is Jeremy Davis available?" a voice asked. Then the caller added: It's Tim Pawlenty.
So began a crucial political courtship as the miles rolled by on I-35 -- one more sign of how the former Minnesota governor's presidential campaign is being built in this early caucus state, one operative at a time.
Davis, 33, is a rising star in Iowa Republican circles. That makes him a valuable foot soldier in the grass-roots network Pawlenty needs in his win-Iowa-or-bust quest for the White House.
No one wins the Iowa presidential caucuses without a thriving political ground game and the support of community leaders like Davis, who can persuade voters -- people who are their neighbors and friends -- to express their presidential preferences in public on caucus night.
Eventually Pawlenty's campaign across Iowa will be a traditional blitz of television commercials, yard signs and doorknocking. Right now, the name of the game is locking up local leaders.
"It's really about making the connection with the activists," said Eric Woolson, another key Pawlenty recruit who managed Mike Huckabee's winning 2008 caucus campaign in Iowa. "It's the epitome of retail politics, very much word-of-mouth and personal relationships."
