On Saturday morning, Wiederaenders stole time from his family to volunteer for another two-hour canvassing shift that included 44th Street.
Some neighbors rebuffed him -- politely -- saying they were backing someone other than Obama. A few, including the Gentrys, didn't answer the door. Their cars were parked in the driveway, suggesting they may have been ducking the conversation.
"It's crazy," Tammy Gentry had said in an earlier interview. "I bet we have, nightly, three to five telephone calls. . . . I don't mean to portray this as negative. We're so fortunate to have all these great candidates here. It's just the daily grind. It just gets to you."
At some doors, Wiederaenders entered into something like electoral conspiracy.
But some, Wiederaenders acknowledged, were beyond his reach.
As he walked down the steps at the home of fellow Obama-supporter Tonya Swanda, who had been lobbying Tammy Gentry to back the Illinois senator, Swanda pointed to the fresh Edwards sign in the Gentry yard next door.
"I guess we lost Tammy," she said.
"Yup," Wiederaenders said, "we lost Tammy."
