A more informal poll of San Diego residents this week outside City Hall mirrored those findings.
But one resident, interviewed by CNN iReporter Chris Morrow, explained why he still supports Filner.
"He's actually really good for this city's population, especially the homeless population out here; I know he definitely cares about them ... I think it'd be a very, very bad move to see that gentleman resign."
Another man, who identified himself as homeless, disagreed.
"I actually voted for Filner ... he was a good man, I like what he's doing for the homeless, 'cause I'm homeless myself. But for something like that to go on, and people actually stepping up, and him admitting to what he had done, I do believe he should resign."
