MANILA — Vice President Sara Duterte remains ahead of Naga City Mayor Leni Robredo in a hypothetical two-way presidential race for 2028, according to a new Pulse Asia survey commissioned by Stratbase Group.

In a report, it said that the survey, conducted from May 3 to 7, 2026, showed Duterte receiving 51 percent support, while Robredo got 41 percent. Eight percent of respondents were either undecided or declined to state their preference.
