Proberz Research and Consultancy, a survey outfit used extensively by former President Fidel V. Ramos, has come out with its survey on senatorial aspirants who have the best chance of winning in the 2004 elections.
Proberz has not yet attained the stature of Social Weather Stations or Pulse Asia but I remember it to be the only survey outfit that had Fernando Poe Jr. leading Arroyo by 4 percent in its exit poll in the May 2004 election,. SWS had Arroyo leading by 8.5 percent.
Election results in Metro Manila proved SWS wrong. Much, much later, after the “Hello Garci” tapes came out, Proberz was proven correct.
