Mariel Hemingway 
on Roseanne Barr’s 
presidential run: ‘Are you kidding me?’

Mariel Hemingway might be passionate about many things in her life, but don’t expect her to be joining her former co-star, Roseanne Barr, on a political soapbox anytime soon.

The Academy Award-nominated “Manhattan” actress, who says her favorite flick is the classic film “Mr. Smith Goes to Washington,” isn’t a big fan of celebs who use their fame to hop on the political trail: “I don’t like that. I mean, I’m not well-versed enough in anybody’s positions to really do something.”

Hemingway, 50, played a lesbian in two episodes of “Roseanne,” and even shared a kiss on the show with the ’90s sitcom’s star.

When she heard Barr announce earlier this month that she was seeking the Green Party’s nomination in the presidential race, Hemingway recalls, “I’m following her on Twitter and I’m like, ‘Are you kidding me?’ ”

Hemingway adds that the move “takes away from somebody who might actually get in,” saying, “But God bless her, she has a passion for green and the environment and I love that. What’s disturbing about that is the idea that you think that you’re actually going to make a difference when it’s hard, especially as a celebrity, it’s … hard to be taken seriously anyway. I mean, she’s Roseanne. It’s, like, she’s a comedienne.”

One topic that’s no joke to the entertainer, who’s producing a film based on a book by her famous grandfather, Ernest Hemingway, is health. The bubbly blonde appeared at the Cannon House Office Building last Thursday as the official spokeswoman for SpaFinder.com’s “Wellness Week” — an effort to promote a healthy lifestyle.

The California native says even hustling and bustling Capitol Hill workers, along with Washington’s bevy of on-the-go lawmakers, can make a little time for themselves, explaining, “Politics is their job. Their life is every second of every day. You can be passionate about what you’re believing in and what you’re out doing, but you also have to create an understanding and have a passion for what you’re doing with your own personal being.”
