In an interview Thursday with CNN affiliate WJAR in Providence, Rhode Island, the onetime vice presidential candidate also said the Obama campaign made a mistake in taking aim at her remarks.
"I do think this was a mistake on part of the Obama campaign," she said. "They didn't have to do this, and they did it to hurt Hillary. I just think that's bad. I think it's bad business, and I think it's bad politics.
"I was accused of being divisive. I think those tactics are divisive," she added. "And the amazing thing is it's not something I started, its something they did in reaction to this."
Ferraro also implored Obama's campaign to turn "the spigot off the hate mail I am getting."
"I find it very, very upsetting," she said. " I've been called all kinds of names, and the attacks are ageist, they're sexist, they're racist. It's been very, very uncomfortable.
Ferraro resigned her fundraising post with Clinton's campaign on Wednesday, after taking heat for telling a newspaper last week that Obama's campaign was successful because he was black.
The Illinois senator's campaign denounced the comments on Tuesday and Obama himself called them "patently absurd." Clinton said she repudiated the remarks, though did not publicly call for Ferraro to resign.
In the interview Thursday, Ferraro suggested she did not regret making the comments, saying she was "talking to the facts," and that the issue of race has been raised several times in the campaign before, including by Obama himself.
"The enthusiasm you get from the black community over this black candidate is wonderful, and I don't think you can deny it," she said. "No more than I remember how people felt when I was running."
Ferraro, who was Walter Mondale's running mate in 1984, was the first woman to appear on a major presidential ticket. She has said she raised about $125,000 for Clinton's campaign.
