For her part, Legarda said she will continue to keep the public trust.
"I am both humbled and honored. To be trusted by the people in this age of cynicism and skepticism is the best compliment an aspiring public servant can hope to get," Legarda said.
Legarda was the topnotcher in Senate elections in 1998 with over 15 million votes. The former broadcast journalist topped a similar trust ratings survey held by Ibon Facts and Figures late last year.
Legarda also emerged as number one in six senatorial surveys conducted by Pulse Asia, the Social Weather Stations (SWS), Ibon and another survey conducted by a foreign-based pollster.
"The people’s trust is earned, not demanded. A tyrant cannot decree it in place of fear," she said.
Legarda said trust comes from a proven track record of public service.
"I have fought the good fight in exposing the truth about the 2004 elections. I thank all Filipinos for acknowledging that I am doing this for them," she said.
