Davao City Mayor Rodrigo Duterte ranked third anew in the June survey with 15 percent from 12 percent in March.
Interior Secretary Manuel “Mar” Roxas II and former President and now Manila Mayor Joseph Estrada were tied in fourth place with 10 percent each.
The survey, conducted from May 30 to June 5, covered 1,200 respondents, 18 years old and above. It had a margin of error of plus or minus 3 percentage points. The respondents were asked, “Of the people on this list, whom would you vote for President of the Philippines if the 2016 elections were held today and they were candidates?”
Also on the list were Senators Miriam Defensor-Santiago (6 percent from 9 percent) and Alan Peter Cayetano (2 percent from 3 percent) and former Sen. Panfilo Lacson (2 percent from 1 percent).
