BEECH GROVE, Ind. -- An Indiana railroad worker will be among those getting a moment at the Democratic convention to try to portray Barack Obama as the people's champion and counter GOP characterizations of him as an out-of-touch celebrity.

Mike Fisher, an Amtrak machinist from Beech Grove, will talk about Obama's April visit to his house for a lunch of Subway sandwiches.

"When I saw that motorcade come down the cul-de-sac, I couldn't speak, I couldn't swallow. Within a couple minutes, he put us at so much ease," Fisher said. "I'm just a poor railroader. I've got a small house, and a family I'm trying to raise. Barack and Michelle can relate to that because of their upbringing."

Fisher joked that his family is the "whole ball of wax" when it comes to Obama's campaign platform.

He's worried about job security. Two of his children are struggling to pay college loans. His son has a new baby and no health insurance, and his son-in-law is in the National Guard facing possible deployment to Iraq.

The four-day convention starts Monday in Denver.
