Small-business owners can also be a big asset for political campaigns because of their connections and stature in a community. Cynthia McClain-Hill, president of the National Association of Women Business Owners, supports Sen. Obama and in late May hosted a breakfast fund-raising event for him at her downtown Los Angeles law firm. About 130 clients, colleagues and acquaintances attended the event, which included a speech by Sen. Obama’s wife, Michelle. Ms. McClain-Hill raised about $70,000 for the Obama campaign.
