Venezuelans voted Sunday on a wide-ranging package of constitutional reforms.

;CARACAS, Venezuela (AP) – Hugo Chávez sought to cement his power Sunday in a vote on constitutional reforms that could let him remain president for life, a critical test for a leader bent on turning this major U.S. oil provider into a socialist state.

Opponents fear a plunge toward dictatorship. Supporters have full faith that Chávez will use the reforms to deepen grass-roots democracy and more equitably spread wealth.

Venezuelans turned out in high numbers in a vote some pollsters predict will be close. An emboldened opposition and violent clashes in recent weeks prompted fears of bitter conflict if either side disputes the results. Polling stations with lines remained open into the evening. No official turnout figures were available.

“I’m very sure that everything is going to go very well,” Chávez said after voting, holding his newborn grandson in his arms. “We’re going to accept the results, whatever they are.”

Two pro-Chávez officials told The Associated Press their exit polls show a victory for the reforms, but an opposition campaign official said its poll shows Chávez headed for defeat. All spoke on condition of anonymity because of election rules barring the early release of results.

The changes would create new forms of communal property, let Chávez handpick local leaders under a redrawn political map, permit civil liberties to be suspended under extended states of emergency and allow Chávez to seek re-election indefinitely. Otherwise, he cannot run again in 2012.

“He’s going to be an elected dictator,” said 77-year-old voter Rubén Rozenberg.

The retired blue jeans maker, who emigrated from Cuba in 1961, said that although Chavez’s revolution is peaceful compared to that of Fidel Castro, “we’ve been violated all around” by the Venezuelan leader’s progressive consolidation of power.

Across town, in a pro-Chávez slum, Jorge Blanco, a 40-year-old motorcycle taxi driver, said Chávez “is giving power to the people” through the reforms. “He opened that little door and now we’re free.” Of the wealthy elite, Blanco said: “What they fear is losing power.”

Chávez has warned opponents he will not tolerate attempts to stir up violence, and threatened to cut off oil exports to the United States if Washington interferes. The United States is the No. 1 buyer of Venezuelan oil.

Latin America’s most outspoken foe of Washington, Chávez calls those who resist his socialist agenda pawns of President George W. Bush.

While his government touted pre-election polls showing Chávez ahead, surveys cited by the opposition indicated strong resistance – unfamiliar for a leader who easily won re-election last year with 63 percent of the vote.

Chávez has accused the U.S. government of plotting to thwart the legitimate victory he predicted.

Sen. Carl Levin, a Michigan Democrat who chairs the Armed Services Committee, denied any U.S. attempts to undermine Chávez.

“We’re not seeking to destabilize him. His policies, his efforts at dictatorship, to amend the constitution so he can stay there for life, that is what’s destabilizing Venezuela, not our policies,” he told CNN.

Casting his ballot, Chávez called the electronic voting system “one of the most modern in the world, one of the most transparent in the world.”

His opponents have questioned the National Electoral Council’s impartiality, however, especially after Chávez named its former chief, Jorge Rodriguez, vice president in January.

About 100 electoral observers from 39 countries in Latin America, Europe and the United States were on hand, the electoral council said. Absent were the Organization of American States and the European Union, which have monitored past votes.

All was reported calm during voting but 45 people were detained, most for committing ballot-related crimes like “destroying electoral materials,” said Gen. Jesús González, chief of a military command overseeing security.

At a polling station in one politically divided Caracas neighborhood, Chávez supporters shouted “Get out of here!” to opposition backers who stood nearby aiming to monitor the vote count. A few dozen Chavistas rode by on motorcycles with bandanas and hats covering their faces, some throwing firecrackers.

Opponents – including Roman Catholic leaders, press freedom groups, human rights groups and prominent business leaders – fear the reforms would grant Chávez unchecked power and threaten basic rights.

Cecilia Goldberger, a 56-year-old voting in affluent eastern Caracas, said Venezuelans were being hoodwinked and don’t really understand how Chávez’s power grab will affect them.

She resented the pre-dawn get-out-the-vote tactics by Chavistas, including fireworks and reveille blaring from speakers mounted on cruising trucks.

“I refuse to be treated like cattle and I refuse to be part of a communist regime,” the Israeli-born Goldberger said, adding that she and her businessman husband hope to leave the country.

Chávez sought to capitalize on his personal popularity ahead of the vote.

He is seen by many as a champion of the poor who has redistributed more oil wealth than any other leader in memory. Chávez, 53, says he will stay in power only as long as Venezuelans keep re-electing him – but has added that might be until 2050, when he would be 95 years old.

The reforms would also grant Chávez control over the Central Bank and extend presidential terms from six to seven years.

Many Chávez supporters say he needs more time in office to consolidate his brand of “21st century socialism,” and praise other proposed changes such as shortening the workday from eight hours to six, creating a social security fund for millions of informal laborers and promoting communal councils where residents decide how to spend government funds.

Tensions have surged in recent weeks as university students led protests and occasionally clashed with police and Chavista groups. One man was shot dead Monday while trying to get through a road blocked by protesters.

Some 140,000 soldiers and reservists were posted for the vote, the Defense Ministry said.

Electoral council chief Tibisay Lucena called the vote “the calmest we’ve had in the last 10 years.”
