The formation of the Los Angeles County Business Federation was announced at a press conference this morning at the Los Angeles Hall of Administration. The group will include more than 40 organizations. Tracy Rafter, former publisher of the Los Angeles Daily News, will serve as chief executive of the group. David Fleming, outgoing chairman of the Los Angeles Area Chamber of Commerce, will serve as chairman of the federation. The group’s aim will be to obtain political sway by mobilizing trade groups, chambers of commerce, businesses and business groups. A Web site the federation will host will play a key role in mobilizing members of the business community, as it will give businesspeople access to the contact information of legislators, allowing them to rapidly air their concerns and have their needs addressed.
