Portugal Colonial - Argentines vote in cliffhanger election with economy at stake

The two men represent starkly different futures for Latin America's third-largest economy, creaking under triple-digit inflation and poverty levels over 40 percent.

Polls show the candidates in a dead heat, with Milei holding such a slight advantage that no one wants to predict an outcome.

Some 36 million Argentines will be able to vote until 6:00 pm (2100 GMT), with results expected a few hours later. The new president will take office on December 10.

Massa, 51, is a charismatic and seasoned politician seeking to convince Argentines to trust him despite his performance as economy minister which has seen annual inflation hit 143 percent.

His rival Milei is an anti-establishment outsider, who has vowed to halt Argentina's unbridled spending, ditch the peso for the US dollar, and "dynamite" the central bank.

Argentines are "on the edge of a nervous breakdown," said political analyst Ana Iparraguirre of GBAO Strategies, describing tensions over what comes next.

Most are so disgusted with their options that "they're going to have to choose the lesser of two evils."

Turnout will be crucial with polls showing about 10 percent of voters still undecided, and the election taking place on a long weekend.

"Neither of the two candidates have good proposals. I voted for the one who will do the least damage to the country which is in a very complicated situation," said nurse Laura Coleman, 25.

- Milei puts down chainsaw -

Milei, a 53-year-old economist, is a political newcomer who stunned observers by surging to the front of the electoral race just months ago.

He is often compared to former US president Donald Trump and Brazil's Jair Bolsonaro, with Massa accusing him of aping the two politicians by raising the specter of electoral fraud -- for which he has provided no evidence.

Milei's rants against traditional parties who have failed to halt decades of economic decline have fired up voters tired of the status quo.

"I hope Milei wins," said taxi driver Daniel Ayala, 50, adding he was "tired of the corruption" of the ruling Peronist coalition.

In a first-round election in October, Massa confounded the polls by coming first with almost 37 percent, while Milei scored about 30 percent of the vote.

Both have scrambled to shore up millions of votes from the three losing candidates.

Third-placed candidate Patricia Bullrich, from the powerful center-right opposition, has thrown her weight behind Milei.

Milei has toned down his rhetoric to appeal to her more moderate voters, imploring the public not to give in to fear stoked by Massa's campaign.

"If you are afraid you will be paralyzed and... nothing will change. We are not going to privatize health and education, we are not going to allow the unrestricted carrying of guns," he said.

He previously said he was going to ditch those ministries entirely and was in favor of making it easier to carry guns and even sell human organs.

In recent weeks there has been no sign of the powered-up chainsaw he used to wield at rallies -- a symbol of cuts he wanted to make to public spending.

- Calm alternative -

Massa represents the Peronist coalition, a populist movement heavy on state intervention and welfare programs that has dominated Argentine politics for decades.

He has sought to distance himself from the deeply unpopular outgoing President Alberto Fernandez and his Vice President Cristina Kirchner, who was last year convicted of fraud. Both have vanished from the public eye.

Massa has sought to portray himself as the calm, statesmanlike opposite of Milei.

However, analysts accuse him of abusing state resources to boost his electoral chances.

This includes using ads to warn that transport prices would increase under Milei as well as slashing income taxes for almost the whole population and granting cash payouts to millions.

- 'Unbelievably deep hole' -

Whoever wins, analysts warn Argentina is in for a tough road ahead.

Analysts say the strictly controlled peso is long overdue for a devaluation, and a lack of dollars has led to shortages in fuel, medicine and even bananas in recent weeks.

With central bank reserves in the red and no credit line, the next government "will be digging Argentina out of an unbelievably deep hole with very few resources to do so," said Benjamin Gedan, director of the Argentina Project at the Washington-based Wilson Center.
