Brazil President Dilma Rousseff narrowly trailed challenger Aecio Neves in latest opinion polls ahead of their Oct. 26 election showdown, a survey showed Thursday.
Neves, who upset predictions to eliminate environmentalist and early front-runner Marina Silva in Sunday's first round, was polling 46 percent to 44 for Rousseff, the Ibope poll for Globo television and Estado de Sao Paulo newspaper showed.
