Thousands marched through the Venezuelan capital on Saturday to oppose President Hugo Chavez's plans to allow unlimited reelection for officials, including himself.
To cries of "no means no" demonstrators -- led by opposition parties and student groups -- marched 18 kilometers (11 miles) from the outskirts to the center of the Caracas.
Local media reported as many as 600,000 people took part in the protest.
The show of strength comes ahead of a February 15 poll, when Venezuelans will vote on whether to strip term limits from the constitution.
"I am voting 'no' because I don't want the president to stay in office after 2012, he wants to monopolize everything" said Rolando Gonzalez, a worker from the densely populated Catia neighborhood of Caracas.
With his popularity dipping, Chavez has vowed to promote economic development and address mounting crime worries if he wins a third term.
"Those who want to go on a direct route to violence, ungovernability and chaos, should vote 'no,'" he recently remarked.
- CHAVEZ COULD MAKE GOOD ON THE THREAT OF VIOLENCE; I PREDICT HE DOES - IF HE LOSES.
- GOD BLESS THE ANTI-CHAVEZISTAS!
- WE'LL BE MARCHING LIKE THIS SOON IN THE USA - AGAINST OBAMA!
