Just about a year and a half ago, Sen. John McCain went to court to try to curtail the influence of a group to which A. Jerrold Perenchio gave $9 million, saying it was trying to "evade and violate" new campaign laws with voter ads ahead of the midterm elections.

As McCain launches his own presidential campaign, however, he is counting on Perenchio, the founder of the Univision Spanish-language media empire, to raise millions of dollars as co-chairman of the Arizona Republican's national finance committee.

In his early efforts to secure the support of the Republican establishment he has frequently bucked, McCain has embraced some of the same political-money figures, forces and tactics he pilloried during a 15-year crusade to reduce the influence of big donors, fundraisers and lobbyists in elections. That includes enlisting the support of Washington lobbyists as well as key players in the fundraising machine that helped President Bush defeat McCain in the 2000 Republican primaries.
