And a good part of this success, analysts say, stems from his affiliation with a well-established and politically connected law firm that is based in Houston and bears his name, Bracewell & Giuliani.

That affiliation adds to Mr. Giuliani?s personal wealth but also could pose political risks for him. The firm is perhaps the nation?s most aggressive lobbyist for coal-fired power plants, heavy emitters of air pollutants and carbon dioxide, a gas associated with global warming. Environmentalists say the firm played a significant role in persuading the Bush administration to roll back major provisions of the Clean Air Act.
