When asked if they would vote by mail, 43 percent of the 436 votes cast answered "No" while 35 percent said "Yes."
Some 22 percent opted to vote for the "Wait, I have questions" option.
The survey was conducted by Comelec Spokesman James Jimenez via his Twitter account @jabjimenez for 24-hours starting Monday.
On Friday, Comelec Commissioner Rowena Guanzon pushed anew for mail voting in the May 2022 national and local polls.
She believes the turnout of votes will be "high" if there is also mail voting.
"More PWDs elderly, pregnant women can vote if by mail," Guanzon said in her Twitter account @rowena_guanzon
But the poll official said the Philippine Postal Service must be "efficient and impartial."
Last September, Guanzon also backed House Bill 7572 of Marikina (2nd District) Representative Stella Quimbo which will allow senior citizens to vote by mail amid the coronavirus disease 2019 (COVID-19) pandemic.
Voting by mail is already being used by the Comelec in overseas voting.
