MEXICO'S RULING PARTY LOSING HOLD ON POWER

Vicente Fox of Mexico's conservative National Action Party (PAN) won the most lopsided major election victory ever over the country's Institutional Revolutionary Party (PRI). The PRI, which has dominated Mexican government since its inception in 1929 and did not allow a candidate from another party to win a state governor's election until 1989, got only 30 percent of the vote in the race for governor of Guanajuato, one of Mexico's largest states. Fox, a former Coca Cola executive, is expected to run for the presidency in 2000.
