"I'm voting for Bernie Sanders, because he doesn’t take any corporate money," the undefeated UFC champion told Maxim in an interview published Tuesday. "I don't think politicians should be allowed to take money for their campaigns from outside interests."
She continued: "If he doesn’t win against Hillary, then I’ll probably vote for a third party again. To be honest, in 2012 I was against both candidates and so I just picked any third party because I thought if more people voted for third parties then they'd have to take third parties seriously."
Rousey's third party pick in 2012 was comedian Roseanne Barr, who ran on the Peace and Freedom ticket and placed 6th.
Rousey joins a number of other celebrities backing Sanders in the Democratic primary, including Will Ferrell, Susan Sarandon, Danny DeVito, Mark Ruffalo, Steve Wozniak, Wilco's Jeff Tweedy and Bonnie Raitt.
Democratic frontrunner Hillary Clinton also has a number of high-profile names on her endorsement roster, including Kim Kardashian, Katy Perry, Robert DeNiro, Lena Dunham and Magic Johnson.
HuffPost Pollster, which tracks all publicly available opinion polls, shows Sanders polling at 30.8 percent nationally, while Clinton is at 55.5 percent.
