¡¡¡¡REFERENDUM AT STAKE

¡¡¡¡The Colombian government expects to receive 6.268 million votes,both positive and negative, but the goal was believed to be challenging as abstentions are high among Colombian voters.

¡¡¡¡Opposition parties and illegal armed groups campaigned to blockthe referendum, accusing Uribe of trying to "cover the fiscal deficit" and preparing for re-election in 2006 by holding the referendum.

¡¡¡¡The president, who proposed the referendum when he took office on Aug. 7, 2002, said on Saturday that it is a step to fight corruption and to "strengthen the public order."

¡¡¡¡In the referendum, the government proposed freezing wages and pensions for government officials, reducing the size of Congress and fighting corruption, but local analysts say the government needs more drastic fiscal and pensions reforms.

¡¡¡¡Members of the Liberal Party, who are major opponents to the referendum, expected the referendum to fail and said it would represent a "victory" for the opposition.

¡¡¡¡A year after taking office, Uribe now enjoys a 70-percent approval rate. But analysts said his approval rate could drop if the referendum fails and harsh economic measures continue. Unemployment could reach 17 percent under current economic circumstances, they warned.

¡¡¡¡Other political analysts anticipated that if the referendum wasapproved, pro-Uribe congressmen would be encouraged to move ahead with efforts for Uribe's re-election.

¡¡¡¡Colombia has been plagued by a four-decade civil war. The conflict kills about 3,500 people every year, most of them civilians. Enditem
