Having tread on one too many toes with her comedy, Roseanne Barr now lives in self-imposed exile in Hawaii -- literally on a nut farm.
Her home is a 46-acre macadamia nut farm in the mountains of Honakaa.
"I was not prepared for the crash of like the crazy crash of celebrity," she said, "I'm one of these people that has, I call 'em my fans, people who love to hate me."
Watch the full interview with Roseanne Barr on "Nightline" tonight at 11:35 p.m.
But she's back with talk of a new reality show and the release of a third book -- part autobiography, part political rant.
"Roseannarchy: Dispatches From the Nut Farm," released Jan. 4, accuses Sarah Palin of stealing her act, takes aim at celebrities in general and retraces Barr's own spiritual and cultural odyssey from her beginnings as a "fat Jewish girl" in Mormon Utah.
In the book, the 58-year-old performer described her path to fame and fortune as a "deal with the devil." To Barr at least, the devil looks an awful lot like her ex-husband, actor Tom Arnold.
"Everyone I've met in Hollywood made a deal somewhere to remain silent about abhorrent things in order to remain popular," she told "Nightline." "They decide, well, these are safe topics that I can speak out on but not this, because this will cut into my money."
Barr decided long ago that it was no longer a compromise she was willing to make. She continued to make her voice heard in very public ways.
Last May, on Mother's Day, she stood with a bullhorn in Lafayette Park in Washington, D.C., across from the White House, to announce her candidacy for both U.S. president and prime minister of Israel.
"This is a two-fer," she said. "I'm running on the new Green Tea Party ticket." Her platform is to fix all the world's problems herself.
Barr said she sympathized with the Tea Party movement and shared its anger.
"I understand a revolt by American taxpayers who are getting nothing for paying these huge taxes," Barr said. "But the solution is for the American public to have some say in how public money is spent. And I believe that public money needs to be spent on the American public, not these private contractors who Sarah Palin works for."
Barr said she doesn't like Palin, even though the two could both be described as brassy, blue-collar feminists.
"I feel she's ripping off my act," Barr said. "She's not even telling the truth to the American people. I think she took a lot from me and from my show, absolutely."
Barr had strong words for President Obama as well. "I didn't vote for him," she said. "I did NOT want Obama to be president of the United States."
Nor does she think highly of Obama's accomplishment on passing a health care law.
"I think it's a bunch of crap," she said, noting that she favored the public option. "I think the American people deserve to have health care like every other country."
Barr's intense interest in current events helped make her sitcom, "Roseanne," the No. 1 show on television in the early '90s, reaching an audience of 36 million people at its peak.
