Mr. Shaddock's outspokenness on these views, which the campaign has asked him to rein in, was not tested on Tuesday night as he placed calls to voters. Using an app, Ground Game 2, supplied by the Trump campaign, which also provided a list of prospects in his precinct, he placed calls to all eight names - as many as he had been given for the day by Trump headquarters.Six times he reached voice mail messages. Another number was not in service. At the one number he reached, a woman picked up, and Mr. Shaddock asked to speak to the voter on his list, a man.
"I don't know that person," the woman said.
"I did dial the correct number, right?" Mr. Shaddock asked.
The woman hung up.
In Fairfield, in southeast Iowa, Mr. Shaddock, the 9/11 skeptic, said it would be difficult to find someone to speak publicly on Mr. Trump's behalf in each of the eight precincts in the area. He asked the Trump campaign for $500 to rent the Fairfield Arts and Convention Center so all precincts could caucus together, which would require just one speaker. The campaign turned him down. "Donald himself could have spent $500," he said.
