Davao City Mayor Rodrigo Duterte topped the latest Social Weather Stations (SWS) Survey with a score of 27 percent. Grace Poe, formerly at the top, is now second with 23 percent.
Vice President Jejomar Binay secures third place with 20 percent, closely followed by former Interior Secretary Manuel Roxas II at 18 percent. Miriam Defensor Santiago is the least preferred presidentiable, with only 3 percent.
Duterte's surge to the top is attributed to his performance in the March 20 televised presidential debates.
Previously conducted surveys such as the March 8 to 11 poll and the March 30 Bilang Pilipino Mobile Survey highlight the volatility of Duterte and Poe's position. While Duterte's score increased by four points from his March 8 to March 11 SWS poll rating, he is down by four points from his 31 percent score in the March 30 Bilang Pilipino Survey.
Meanwhile, Poe is currently six points down from her 29 percent score in the March 8 to 11 survey, and down by 11 points from her 34 percent in the mobile survey.
Binay's position is relatively stable; his latest rating is two points lower from his 22 percent in March 8, but three points higher from the 17 percent in the mobile survey.
Roxas is also fairly stable; he is only one point lower from his previous 19 percent last March 8 to 11, and one point higher from 17 percent in the mobile survey
Santiago has scored the lowest in the three surveys, maintaining her 3 percent from the last March 8 to 11 survey, and 1 percent in the mobile survey.
The First Quarter 2016 Social Weather Survey was conducted last March 20 to April 2 by means of interviewing respondents face to face. A total of 1,377 or 92 percent out of the 1,500 respondents were validated as registered voters. The poll has a +/-3 points sampling margin of error.
The March 8 to 11 poll was the last time face to face interviews were used, while the mobile poll was answered through mobile phones. The mobile poll, however, used the same respondents as in the March 8 to 11 survey.
For the vice presidentiables, Senator Bongbong Marcos takes the top spot, with over 26 percent . Senator Chiz Escudero now ranks 21 percent, a considerable decrease from his previous rank at 28 percent. Congresswoman Leni Robredo takes third place at 19 percent, followed by Senator Alan Peter Cayetano at 13 percent. Lastly, Senator Gringo Honasan and Senator Sonny Tillanes are tied for fourth place, with 5 percent.
