Brazil's Neves rides calm, pro-business message into election runoff

By Caroline Stauffer

SAO PAULO, Oct 5 (Reuters) - In Brazil's most unpredictable election in decades, it was the candidate with the old-school family pedigree and a calm, presidential air who turned the race upside down with a dramatic late surge.

Stuck in third place and all but written off just a week ago, Senator Aecio Neves, 54, comfortably grabbed second place in the first round of voting on Sunday and will face President Dilma Rousseff in a runoff on Oct. 26.

He now has three weeks to convince voters who backed the candidates eliminated on Sunday that his brand of austere, pro-business policies are the best bet to lift Brazil from three-plus years of economic stagnation.

Neves' image as an insider from the biggest opposition force, the centrist Brazilian Social Democracy Party (PSDB), was a problem throughout much of the campaign.

Voters looking for change after four years of Rousseff's leftist rule threw their support behind a more novel candidate who promised a break with politics as usual - environmentalist Marina Silva.

But when attack ads and Silva's own unpredictable behavior hit her campaign, opposition voters went running back into the reassuring arms of Neves.

He won almost 34 percent of the vote on Sunday. He trailed Rousseff by around 8 percentage points so she is a slight favorite to win the runoff.

But recent polls showed that more than half of Silva's supporters would back Neves in the runoff, while only a quarter were leaning toward Rousseff and the rest were undecided or said they would spoil their ballots in protest. Silva had around 21 percent support in Sunday's election.

Neves started his political career at age 21 as an aide to his grandfather. Tancredo Neves was set to become president in 1985 as Brazil emerged from a dictatorship, but died of an infection before taking the oath of office.

He remains a popular figure. Aecio Neves still mentions him regularly and posted a photo of him on Facebook the night before the election.

Those deep political roots could still work against Neves. Both he and the PSDB, which last governed Brazil from 1995 to 2002, are widely perceived as elitist - a problem in a country where more than half of voters live in households earning less than $1,000 a month.

But for now, his broad party support and reputation as a skilled builder of coalitions have convinced many Brazilians that he is qualified to lead a continent-sized nation of 200 million people.

"Mine will be a government of predictability, because that will be essential for the market and investors to again be partners in our national development," Neves said on Saturday.
