A conservative billionaire is the favourite in Chile's presidential election this weekend and is expected to go on to win a January run-off, ending 20 years of centre-left rule in Latin America's most stable economy.
A victory by businessman Sebastian Pinera would mark a shift to the right in a region dominated by leftist leaders, but few see major changes to the policies that have made world No.1 copper producer Chile a model of prudent economic management.
Harvard-educated Pinera, 60, runner-up in Chile's last election, is seen taking the most votes out of a field of four candidates on Sunday with former president Eduardo Frei from the fragmented center-left ruling coalition likely to come in second.
Unless one candidate gets more than 50 per cent of the vote, which is not expected, the two front runners will head to a second round on January 17. The run-off is expected to be a close race, although polls show Mr Pinera with an edge.
Mr Pinera vows to create a million jobs and boost growth to six per cent a year through tax incentives and labour sector reforms, and to improve the efficiency of state copper giant Codelco as the economy claws its way out of its first recession in a decade.
"If we do the same things we've been doing for the past 20 years, we'll get the same results," Mr Pinera said as his campaign wound down. "Give us an opportunity to do things better."
His critics say he wants to run Chile like a money-hungry business manager, and that his immense wealth and stakes in businesses such as LAN, one of Latin America's biggest airlines, raise conflicts of interest.
Mr Frei, 67, who was president from 1994-2000 and oversaw rising unemployment during the Asia Crisis, pledges continuity with the social programs of President Michelle Bachelet, who is very popular but cannot run for immediate re-election.
Mr Frei has tried but been unable to gain much from Ms Bachelet's 77 per cent approval rating as infighting, defections and voter anger have undermined the centre-left ruling coalition that first formed in the 1980s to fight Gen. Augusto Pinochet's 1973-1990 dictatorship, notorious for human rights abuses.
Mr Frei's campaign posters often carry Ms Bachelet's image and he rarely refers to his own first term.
"I will continue with the path (Bachelet) has marked out," Mr Frei said. "We represent continuity."
The political right has not won an election for 50 years in Chile, a copper, fruit, wood pulp and salmon exporting nation of 16 million people with the highest living standards in Latin America according to the Human Development Index.
Independent dark horse candidate Marco Enriquez-Ominami is polling third and has split the left's vote, endangering Mr Frei's chances by attracting voters who are tired of Chile's traditional parties.
