New Brazil poll shows Silva beating Rousseff in runoff

BRASILIA (Reuters) - Environmentalist Marina Silva would handily beat President Dilma Rousseff if Brazil's October election goes to a runoff, a poll showed on Wednesday, an outcome that seemed unimaginable just a few weeks ago and one that would put an end to 12 years of Workers' Party rule.

Silva would win 43.7 percent of the votes to 37.8 percent for Rousseff in a likely second round of voting, said the survey by polling firm MDA. It was the second poll in less than 24 hours to show Silva ahead in such a scenario.
