Duterte, Marcos take sole leads in latest SWS poll

Metro Manila (CNN Philippines) — Davao City Mayor Rodrigo Duterte took the sole lead in a recent presidential survey by Social Weather Stations (SWS).

The results first published in BusinessWorld revealed that 27 percent of respondents supported Duterte. Although poll had an error margin of + 3 percent, Duterte's lead was wide enough to prevent a statistical tie.

"The new SWS survey affirms the other surveys that has Duterte on the clear lead in the presidential race," Duterte's spokesman Peter Laviña said.

Except for Duterte and Poe, all other candidates saw their numbers rise relative to the previous survey.
