Roseanne has always been, in one way or another, a revolutionary show. Also, half the country did not vote for Trump. "I felt that was very real and something that needed to be discussed and especially about polarization in the family and people actually hating other people for the way they voted, which I feel is not American", Barr said, according to The Hollywood Reporter.
Barr herself has spoken in support of Trump, but the show's producers said the series does not advocate a political stance.
The first season has nine episodes to explore everything from where original characters now find themselves to introducing new characters in the children of Darlene (Sara Gilbert) and DJ (Michael Fishman) - as well as looking at similar issues like the healthcare, which Barr notes is the "whole arc" of the season, and opioid crisis from the original run with the new lens of today's news and culture.
The show's extended family represents a "full cross-section of ideas and beliefs", said Bruce Helford, among the executive producers and actors taking part in a Q&A with TV critics. "There's probably a lot of things Hillary Clinton has done and said that you don't agree with it", she said.
Barr said making her TV counterpart a Trump supporter made sense for the show about a working-class American family.
"I've always tried to have (the show) be a true reflection of the society we live in", Barr said Monday.More news: Outrage as Trump administration ends temporary protected status for 260k Salvadorans

Barr, who sat on the famed Roseanne couch with original cast members including John Goodman and Laurie Metcalf, said she meant to revisit the groundbreaking comedy.
She said she's "not a Trump apologist, and there are a lot of things he has said and done that I don't agree with".
"People feel like they can't disagree and still love and talk to each other", Gilbert said.
Barr is excited about returning after so many years.
As for current events, Barr was asked if she would support Oprah Winfrey for president, which has enjoyed a social-media groundswell after her Golden Globes speech Sunday. "I think that a great way to fight racism is that everybody has a job".
"I love Oprah, like everybody else", she said. That included politicians-as demonstrated in Season 4's "Aliens", when Roseanne meets a state representative, Mike Summers, who is promoting a plan that gives tax breaks to corporations setting up shop in her hometown of Lanford, Illinois.
