American mixed martial artist Ronda Rousey is throwing her support behind the presidential campaign of Vermont Sen. Bernie Sanders, who the undefeated Ultimate Fighting champion says has taking the right approach to financing his 2016 White House bid.

"I'm voting for Bernie Sanders, because he doesn't take any corporate money," Rousey told Maxim. "I don't think politicians should be allowed to take money for their campaigns from outside interests," the 28-year-old added.

Last time around, the Riverside, California-born fighter did not vote for either President Barack Obama or his 2012 challenger, Mitt Romney, she explained to the men's magazine. Instead, Rousey chose comedian Roseanne Barr, the nominee of the so-called Peace and Freedom Party, which advocates "socialism, democracy, ecology, feminism and racial equality."

"Mostly I went in to vote for all the state and local things," she noted. "I was so unimpressed with the whole presidential campaign that I picked whatever third party I saw, and I saw Roseanne and thought, 'That's awesome.' But I'm really pulling for Sanders this time. I hope it works out."

While the martial artist had no trouble sharing her political views with Maxim, much about the woman who might be "the most discussed female athlete in the world" remains a mystery, Yahoo Sports summarized. And while she recognizes her role as a public figure, the athlete does want to maintain some spheres of her life private, the news service added.

"I give so, so much but a lot of the time, it seems like even all of that is not enough," she explained. "I just want to have some parts of my life that are just for me and only me and don't belong to the rest of the world."

Beyond the Sanders endorsement, though, Rousey has recently made a point of speaking out on issues she cares about, Yahoo News noted. When she posed for Sports Illustrated's swimsuit edition earlier this year, for instance, she said she purposely did not lose weight for the shoot.

"When I was 13, I had a crush on this kid who had a stack of (men's magazines) in his room, and I didn't look like any of those girls," she recalled. "It was so hard," Rousey admitted, saying she now wants to take stand for women with body-image issues.
