Roseanne will premiere March 27 on ABC.
TV reporter Soraya Nadia McDonald, a writer for The Undefeated, had asked Barr why Roseanne Conner, the historic protagonist of Barr's groundbreaking 1988-1997 sitcom Roseanne, would have supported Donald Trump for president when, during the show's original run, she spoke out forthrightly against the sort of xenophobia and racism Trump seemed to represent.
In the revival, we'll see Roseanne and her sister Jackie feuding because of the 2016 election; Jackie supported democrat Hillary Clinton and Roseanne supported eventual victor Trump.
Regarding the 2016 election result, Barr said, "I think it was time for us, as a country, to shake things up and try something different". "No one's brainwashed into agreeing with 100 per cent of what anybody says, let alone a politician or a candidate".
"Roseanne" Executive Producer Bruce Helford spoke to press at the Television Critics Association's Winter Press Tour about the decision to include Trump supporters within the well-known Conners family.
The show's creators didn't say if any other characters will be portrayed as Trump supporters. "I think that a great way to fight racism is that everybody has a job".
"I said it, and I'll say again, my show has always been ..."
She did add that she thinks she would be a better president than Oprah Winfrey, Susan Sarandon - and possibly even Trump himself - and reminded critics she did run for office in 2012. "There are a lot of things he's done and said that I don't agree with in the same way there are probably a lot of things Hillary Clinton has done and said you don't agree with".
Barr then drifted into conspiracy town, saying she couldn't vote for Clinton because of Haiti, citing the debunked claim that the Clintons raised hundreds of millions of dollars for a hospital in the country that was never built.
With a reboot of her iconic sitcom, Roseanne, in the works, the star has left the social media site after a long and protracted rant about liberals and Trump. The entire cast joined her, but almost all of the questions were directed at Barr, who discussed her personal politics and why she'd make a better president than Oprah.
"I do love Oprah".
"I love Oprah, like everybody else", she said.
Barr took issue with a reporter asking about Trump's xenophobia ("That's your opinion"), but she did admit that Trump "says a lot of insane sh*t..."
