AFL-CIO Secretary-Treasurer Richard Trumka, while speaking to the United Steelworkers convention in Las Vegas in July, said Mr. Obama is the only candidate left in the presidential race who is on the side of working people.

“There’s not a single good reason for any worker - especially any union member - to vote against Barack Obama,” he said. “There’s only one really bad reason to vote against him: because he’s not white.”

Chris Chafe, executive director of the Change to Win labor federation, which includes the Teamsters and the Service Employees International Union, said he doesn’t think Mr. Obama’s race will be a factor when his members go to the polls in November.

“My experience has always been, and polling proves it out, that union members vote overwhelming in support of the candidate who is going to do the most to help them hold on to the middle class,” he said. “It’s no different in this election than in any other.”
