Sen. Grace Poe and Davao City Mayor Rodrigo Duterte were in a statistical tie in a Bilang Pilipino SWS Mobile Survey conducted on March 30, where close to 60 percent of respondents said they will likely not change their minds on who they want to vote for in May.
Poe had a national score of 34 percent with Davao City Mayor Rodrigo Duterte in second place with a score of 31 percent. Former Local Government Secretary Manuel Roxas II and Vice President Jejomar Binay both had scores of 17 percent while one percent of respondents picked Sen. Miriam Defensor-Santiago. One percent of respondents was undecided.
SWS said the survey has sampling error margins of ±4% for national percentages, ±7% in Metro Manila and Visayas, and ±8% in Balance Luzon and Mindanao because of a decline in the number of respondents since the surveys began.
