Pentacostals Could Impact Presidential Vote in Brazil

A fast-growing evangelical movement could influence the outcome of today's presidential elections in Brazil.

Socially conservative evangelicals have boosted the popularity of opposition candidate Marina Silva, who is a member of a pentecostal church.

Polls show Silva running a tight race against President Dilma Rousseff, who is seeking re-election.

Evangelicals have grown from a tiny minority three decades ago to almost a fifth of Brazil's electorate today, but that might not be enough to elect a pentecostal president.

The latest polls predict that Silva would lose a runoff vote against the incumbent president.
