A PR firm called "The Center" is trying, probably, to deceived the public of who leads the Presidential Elections in the Philippines. Based on a credible survey by the SWS, Noynoy Aquino is on the lead.

A special national survey sponsored by Puerto Princesa City Mayor Edward Hagedorn was conducted by SWS on November 4-8, 2009.
The survey used face-to-face interviews of 1,200 registered voters divided into random samples of 300 each in Metro Manila, the Balance of Luzon, Visayas, and Mindanao (sampling error margins of ±3% for national percentages and ±6% for area percentages).
The Commission on Elections’ latest counts of Registered Voters, by region and area, as of November 2009, were used to weight regional estimates to obtain area estimates, and to weight area estimates to obtain national estimates.
