BRASILIA, Shawwal 22, 1435, Aug 18, 2014, SPA -- Environmentalist Marina Silva will enter Brazil's presidential race in second place with the support of 21 percent of voters and would be tied with President Dilma Rousseff in a second-round runoff, Reuters cited a poll as showing on Monday. Silva has drawn almost three times more support than the late center-leftist candidate Eduardo Campos, who she is expected to replace in the race after his death last week in a plane crash. Support for the leftist Rousseff was unchanged at 36 percent, according to the poll. It showed that Silva would deprive Rousseff of the votes needed to win the Oct. 5 election outright and surpass her in a second-round runoff by 47 percent of the votes against 43 percent, within the poll's margin of error. --SPA 19:59 LOCAL TIME 16:59 GMT www.spa.gov.sa/w
