The Denver Post had a story in their Sunday edition on Denver-area businesses having a hard time getting Democratic National Convention contracts including L&M Pressworks, a Denver print shop. The the article quotes L&M Pressworks Account Executive Charlotte Kulcsar on the companies attempts to get DNC business:

As soon as Charlotte Kulscar heard the Democratic National Committee named Denver its 2008 convention site, she began researching how to get a piece of the estimated $160 million economic impact for her print shop. She thought she had a good shot. L&M Pressworks already does printing for the city, the state and the Downtown Denver Partnership. She filled out the application for the DNC Vendor Directory and was sure to include the shop's status as female- owned and green-certified.

But the company has run into a dead-end everywhere:

"Since this convention is so green, we thought that was going to be the best way to go, but we haven't gotten anything out of it," Kulscar said about her Denver shop, which is Forest Stewardship Council-approved, uses soy-based inks and ensures its paper mills replant the trees they use. "We've run into a dead-end everywhere."
You would think the party of environmentalism would support a FSC-certified, woman owned business. Update As many have pointed out in the comments other factors play into getting these contracts: organized labor and political affiliation being at the top of the list.
