LESS than a week before the elections, independent pollster Pulse Asia on Tuesday said it was impossible for Vice President Maria Leonor 'Leni' Robredo to stage an upset against former senator Ferdinand 'Bongbong' Marcos Jr. or BBM who got 56 percent in the firm's latest and last presidential election survey.

Ana Maria Tabunda, research director of Pulse Asia, said the majority of the 65 million registered voters have already decided at this time and no amount of convincing could make them change their minds about their preferred bets.
