It seems like Ronda Rousey's worldview can be summed up into two words: No excuses.

Which could explain why one of the world's highest-profile athletes has repeatedly sidestepped opportunities to be a warrior for gender equality, equal pay and feminism. She often points to the fact she's earned every penny of her success -- while overcoming family and personal struggles -- without men taking pity on her because she's a girl.

Accordingly, the undefeated UFC champion and Olympic medalist has become something of an icon to some on the right. Over the last nine days, a video of Rousey shutting down questions that invited her to take feminist stances on things like the wage gap has circulated pretty widely, with more than 240,000 views (warning: some strong language in this and the linked videos that follow). Another similar video, from three weeks ago, has 400,000 views. And a third, from three months ago, more than one million.

Accordingly, Rousey's apparently very capitalistic and gender-neutral worldview has endeared her to some on the political right.

And yet, the man Rousey says she's supporting for president wants to close the gender pay gap and give billions of dollars worth of free college education, health care and child care to Americans to help them get a leg up in life.

Which is what makes Rousey's endorsement of Sen. Bernie Sanders (I-Vt.) so interesting. His philosophy on what role society should play for people who are struggling would seem to run counter to the things Rousey says about her own story.

Rousey pulled herself up by the bootstraps, overcoming a speech disorder and then her father's suicide as a child only to struggle later in life then with eating disorders and substance abuse. At 28, she's now one of the highest-paid female athletes in the world, a movie star and one of the world's most recognizable names in athletics.

No handouts got her to where she is today, she repeatedly indicates.

"I'm not the highest-paid fighter because [the sport] wanted to do something nice for the ladies," she said in a press event in Australia in October in response to a question about that country's equal-pay dispute.

Sanders, by contrast, has said it's "not a radical idea" that government should step in and help boost women's wages so they're more equal to men's.

"There is no rational economic reason why women should earn 78 cents on the dollar compared to men, and that has got to change," he said recently.

And yet, in an interview with Maxim published Tuesday, Rousey said she's on-board with and "really pulling for" the democratic socialist candidate. Notably, she gave one reason: Sanders's push to get money out of politics.

"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."

In a world where campaigns essentially outsource much of their jobs to super PACs often funded by billionaires, Rousey is not alone in wanting money out of politics. Calling for as much is one of the biggest applause lines in Sanders's speeches.

"I do not represent the agenda of the billionaire class or corporate America, and I do not want their money," Sanders said to a crowd of 20,000 people in Boston in October.

Campaign finance reform clearly has some bipartisan appeal these days. On the opposite end of the spectrum, not taking money from billionaires (except himself, of course) is also a popular go-to campaign line for one of the GOP's front-runners, Donald Trump.

Trump and Sanders are actually two of politics' best spokespeople right now for getting money out of politics, said Represent.us executive director Josh Silver, who advocates for campaign finance and electoral law reform, in an interview with The Fix published Saturday.

"People mistakenly think this is a liberal issue, and it's just not," he said.

(Even so, Rousey's thoughts on Trump, who Maxim noted once tried to name drop her as a fan, are not as generous: "I don't want a reality TV star to be running my country," she told CNN.)

Beyond campaign finance reform, the individualistic athlete might not agree with a lot of what the socialist presidential candidate stands for. And that's okay, because the lines between right and left are not always as straight as we assume them to be.

But Sanders can and should take pride in the endorsement of someone from such a different worldview: It's one more piece of evidence of his surprisingly dynamic appeal.
