The dilemma? Clinton owes a huge debt to Riordan campaign chairman William Wardlaw, who headed Clinton’s California campaign and stood by him during the scandal-filled days before the New Hampshire primary. Riordan also has endeared himself to Democrats: the millionaire has contributed heavily to big-name Dems like Dianne Feinstein and Bill Bradley. While the Woo camp and state party leaders have asked Clinton to visit L.A., Wardlaw-who has key administration backers in Secretary of State Warren Christopher and U.S. Trade Rep. Mickey Kantor-simply wants the president to stay neutral, and in Washington. A senior White House aide acknowledges the quandary. “We have made no decision,” says the aide. “We have friends on both sides.”
