LAS VEGAS — Over 3,000 Steelworker delegates filled the Las Vegas Bally Hotel convention center last week with raring-to-go enthusiasm for “taking back America for working people” in the 2008 elections. One delegate described it as more like a strike vote than a convention. “The membership is fired up and ready to go. We don’t have to be rallied by the leadership, they just need to turn us loose and tell us where to be,” she said.
